A RDM Equivalent to BLM Triplecast

[Mansion]

I don't get the point?
Unless you want to rework RDM's rotation, which is another topic in its own right.
BLM's triple cast is a utility tool, because movement is much more "dangerous" DPS wise than it is for RDM (or SMN).

A RDM can move quite easily if you know how to use your tools and benefit from them.
Corps à corps and Displacement are straightforward. They come back frequently, you just need to "aim" where you want to land in the case of Displacement.
Dual cast : you can freely move during one GCD. Add a Swiftcast (and slide cast on the first GCD) and you have a fairly comfortable window to move with no DPS loss.
Reprise : the newest addition to RDM, a ranged Weaponskill (so it's instant, you can use it while you run). We don't have final potencies but 300 is quite good for its low Mana cost.
So a slide cast > dualcast >swiftcast > Reprise gives you 3 full GCDs to move (7.5 seconds roughly) while keeping DPS uptime. That's enough to cover any distance I guess.

Although RDM's strength is that you can move once every two GCDs so planning your movements is far easier than any caster.

I'd argue that Triplecast is also a small DPS boost, since more than one spell in BLM's arsenal has a longer cast time than its GCD, and even one second faster cast time can mean the difference in losing a Polyglot charge.

But I agree, RDM has a lower value of necessity for additional tools to render spells instant for movement phases. Non-zero value, still higher value to RDM than SMN, but significantly less than BLM.

Well, yes in that specific case of course.
But I think it's a broader issue of casters and movement. Each DPS caster has their own strengths and weaknesses on this topic, and their own tools. DPS uptime comes from integrating this element in the rotation too. In a way, I fear that it would be walking the path of over simplifying things. The addition of a generic "press here if you need to move" button to each caster would be a bit underwhelming, wouldn't it?
I like the idea of skill gap being in this kind of little elements (just like "good" RDM will keep using Displacement instead of Engagement and stuff)

I 100% agree -- at least as far as each caster dealing with movement periods in their own ways, giving them their own identities. Otherwise you may as well remove Ruin II and just make Triplecast a role action.
Of course this does mean that BLM is kind of the odd man out in this regard, I think, since its movement has been woefully crippled without popping cooldowns that may also have been used for raw DPS, but hopefully some of the changes in Shadowbringers have addressed that to an adequate degree.

That said, while I do agree with such things as adding to a job's skill ceiling, it's a very delicate balance, particularly when it involves creating new tools where the entire fact of their availability to players can determine the player's skill.
For instance, to use your example of Engagement, while it is a "safer" option than Displacement, it could be considered something of a DPS trap tool by some players (particularly ones who think they're better than they really are or want to copy top-parsers, and will persist in using Displacement instead, continuing the trend out of spite), and "optimal" players will find ways to use it as little as possible (as you yourself have demonstrated); same case with Scathe for BLM. In both cases there have been (already!) cries for outright replacement.
On the flip-side, tools like Apocatastasis were primarily used by high-end players at very specific points in a combat engagement, and relatively ignored at lower points in play (which I expect is technically also true of Addle, save for the new players who think role actions are supposed to be part of their rotation and spam it on-cooldown alongside Drain and Break).
When you have tools that aren't used across all skill levels, it can feel something of a wasted space to one group or another. That's what makes something like Triplecast particularly appealing, since "optimal" players will find creative uses to get the most out of it and everyone else can still get their money's worth without feeling a loss.

(as you yourself have demonstrated)

I'm still so proud about this lol.

You have a point indeed, but then we enter the debate of job identity and skill gap. Role actions are a little bonus, and using them only makes a difference in challenging content (although a proper timed Apocastasis is always welcome, yet redundant most of the time because the tanks use their own CDs). I'm not sure there's so much to balance there, I like the idea of providing a set of tools and it's up to the player to understand them and use them efficiently. Otherwise, it's either hard to shine with those or you essentially lose the micro-challenges in rotations and individual jobs. I think it's the underlying fear of healers right now, seeing how their kits are getting similar.
Back to casters, I like the idea of having general "Casting challenges" (MP management, movement, utility, burst) but individual solutions, that's what makes a job enjoyable and special in my opinion.

Which does make the changes to Aetherflow and Lucid Dreaming somewhat unfortunate, since it means SMN and RDM now must rely on the same method for MP management, forcing SMN to take a step backward and preventing an 'individual solution' from being added to the RDM (such as recovering via the use of melee abilities).

But to roll back to the original topic, that doesn't in itself preclude RDM from getting a Triplecast-esque ability in its kit, provided it serves either a different function completely (like Dualcast itself does) or a similar function in a different way (like Light Speed).
Rather, I would more question what the purpose of such a skill would be in RDM's kit, since giving Triplecast to RDM wouldn't necessarily provide more mobility (as RDM already has adequate tools for that), but rather more burst (allowing you to chain Verthunder/aero). It's not really a cooldown that can be argued for RDM on the grounds of personal utility.

[Gruntler]

So, build up to 100/100 and then your rotation becomes Verflare->Verholy->Scorch, and because your mana is still 100/100, your rotation remains Verflare->Verholy->Scorch as a literal 1-2-3 combo?

Sounds awful.

Actually I think Reprise is that Triple cast like ability. Essentially, you sacrifice / delay a melee combo in order to move. Some people will try to play around Dual cast, Swiftcast etc, and some might choose Reprise (which has an impressive 300 potency for now).

Reprisal is definitely RDM equivalent to Triple Cast (albeit more simple to use as it requires no CD management)
As said, RDM already have enough mobility with dual cast + Swiftcast. The addition of Reprise is, I think, mostly aimed for less skilled players.
In any case, it will be better to delay your melee combo than do nothing for an entire gcd.

Strictly speaking, at higher level of player I would say Triple Cast is better because you can use it both for mobility and a slight dps boost (around a third of a FireIV... nothing fancy but it's better than nothing). But having coached many BLM, I can tell you most have no clue on how to use it and how to properly manage their proc for mobility.

In the case of RDM, I agree that a Triple Cast would be more efficient, and as I explained a bit above, I think the best option will be the (displacement /) slidecast / dualcast / (swiftcast), because you won't delay your melee combo and "waste" Mana on movement.

Reprise would be (yet again, like Engagement) a very niche weaponskill in the situation where you need to run around like a headless chicken for some kind of mechanic (I think about the tracking lasers on the 2nd boss of the violet tides dungeon for instance, but longer) but result in a DPS loss if used outside of those situations I guess.

Now maybe the new fights will require caster to move a lot so it could find a use, but right now I don't see it working as efficiently as a SMN Trance or a BLM Triple cast / proc management.
