My concept for Ultimate Skills in FFXIV WIP

Please keep in mind that this is a WORK IN PROGRESS, what is written here is not represented of the final Idea.
Ultimate skills Are powerful (where normal skills are concerned) And Flashy skills that Can only be used sparsely And when certain conditions are met.
Potency: 400
Caster potency: 200 per target
Cooldown: 5-10 minute GCD shared for ALL Ultimate skills
Cast time: 30 sec-2 minutes
Ultimate gauge(?): use a charge skill to channel 100% Max MP into gauge (If, for example, you have 9000 max MP you must channel 9000 MP into the gauge to fill it completely even if you have under 9000 at the time, Example: If you have Max MP of 9000 but only have 6000 when you start channeling you would still need yo channel 3000 MP in order to fill the gauge completely), will be immobile or unable to use other skills until charge is complete or MP is fully drained, using other skill will cancel charge. Whether or not you lose gauge when you break channel is unknown.
Multiple Ultimate's: if one is used the rest will get locked by UGCD (Ultimate Global Cooldown)

Please let me know what you think. I want this to be usable but not abuse-able, useful but not broken.

So... limit breaks?

In a sense. The major difference is that Ultimate Skills are Significantly weaker than a limit break but stronger than your normal skills, As well as there are more than one unique Skill per job, rather than how the LB1&2 are shared among role types. With this you can choose one (of how many ultimate skills you have) to use per Cool down.

400 potency single-target or 200 potency AoE for a 30 second cast time? Unless I'm reading your post wrong, this idea is hopelessly underpowered for something called an "Ultimate Skill". 400 potency on a 30 second cast time puts it at a PPS (Potency Per Second) of 13.33~. To put that in comparison, BLM's Blizzard I hits for 180 potency with a 2.5 second cast time, giving it a base PPS of 72. My Blizzard I already has over 5x the PPS while being 12x faster to cast.

Also your potency choices + Cast time makes it dead weight for all DPS/Tank jobs.

• PLD can use Goring Blade, which does more damage after 12 seconds. Royal Authority does 455 when used with Fight Or Flight.

• MNK can use Tornado Kick, which does about 445.5 potency with GL3 and Fists of Fire.

• WAR can use Fell Cleave, which does ~660 potency (math may be wrong) with Maim and Storm's Eye up.

• DRG can use Life Surge every 50 seconds on any of their combo finishers for better potency. ( ~680 for Full Thrust, ~550 for Wheeling Thrust & Fang And Claw. All three have Heavy Thrust)

• NIN can use a Kassatu'd Raiton every minute or use Duality on Aeolian Edge every 90 seconds. Shadow Fang also does more damage after 15 seconds of uptime.

• DRK can use Dark Arts + Carve And Spit every minute or Dark Arts + Souleater.

• BRD can just combine Rain of Death and Wide Volley for more potency assuming it uses the caster version of your idea.

• MCH can use Grenado Shot or Spread Shot twice.

• BLM can cast Fire II twice with the upside of not spending ALL of your mana.

• SMN can cast Painflare for 200 potency and DeathFlare for double that. Also Bane with all Bio II, Miasma, and Bio will do the same at 6 seconds and beats it after that.

This idea needs a massive overhaul or it's only going to be used as an opener.

I Grossly undershot it so that I could have a base to work off of. Better that than to go full 1K Potency with a shorter Cast/Cool-down time And make people look away, by starting out this low I hope to Have people suggest what would work best in terms of Potency and cast/cool-down time. Suffice it to say this isn't what I would want it to be, however I did not want to propose something that would be broken and make people dismiss this as another player seeking to have an overpowered System added into the game. Anyway I'll just be spinning my wheels if I keep going, I do hope to Keep this discussion going so we can tweak this into being something reasonable with the base Idea that I have written currently.

So once again, you just come back to having a limit break with another name.

I suppose. Granted I want this to be Viable, but not broken, for Solo use. With the way the party LB system works it would understandably be difficult to bring that into the Solo player, seeing as they would have to tweak an already existing system with it now having two uses. And the Adrenaline Rush system is close but from what I've read the gauge fills to fast to be balanced, And again they would have to tweak an already existing system which would probably cause problems with the code. This is merely another version of that which is made specifically for the player(s) who are not in a party or a full/light party. This would also give each player A strong attack to use at their own discretion without having to worry about wasting the LB gauge.

I'd rather players have individual limit breaks(like a actual FF game who would have figured) instead of the party sharing nonsense. PvP already does it with a Adrenaline gauge.

The Problem With The Adrenaline System is that the gauge fills to fast, Plus it has the Potency of an LB1. If anything I would want to expand upon that and Make it interesting for players and give them the option as to which skill they wish to use.

The base idea of self ultimate skill can be interesting, but I'd also see this as a revamped LB system.

But, on top of that, it would be fun to bring back "Skillchains" but for those limit breaks with new animations.
You'd need two healers LB at the same time to Raise everybody, two tank LB to reduce damage by 50%, etc...

You could have a MNK kicking the BLM meteor like a Blitzball ! :D
