Agree on sometimes being hard to follow. And I'm honestly up for most changes as long as they retain AT LEAST ONE healer that is more or less as today. I don't think that's a tall ask, honestly. Or shouldn't be, anyway.
Well, the reason I say what the potencies were - people had a lot of interesting...ideas...about what was and wasn't a DPS gain back then, many of them being wrong. The theorycrafting stage of FFXIV's evolution really came into its own in SB, with fits and starts before then and a lot of people doing things that were sub-optimal. So I'm never quite sure "here's a person using it" means it was good or not. BLM's used Blizzard 2 sometimes.Jokes aside, I think even WHM's could cross-class it. Did NOT get the MP regen effect, though.
Agree on BLU. I like things like that. The thing is, they need to be GCDs with shortish (15-30 sec max) CDs. Otherwise we end up with Assize weaves. But the trick is also not to fill Jobs with needless button bloat. MCH, for example, has 4 "big CD" buttons, each a separate button...but you effectively use them on CD outside of some very niche optimization. Drill, Air Anchor, and the new sawblade one. They could honestly replace them with one button that cycles through each every 15-20 sec (this is literally how PvP MCH works) and nothing of value is lost other than unneeded hotbar bloat. So there's kind of a careful balance there. And I don't mind stuff like Phlegma for but Hydaelyn's sake, don't make it melee ranged! I HATE melee ranged stuff on my caster/ranged classes (and healers are a caster). I already dislike that on RDM, but it's part of the class fantasy there, at least. It isn't with Jobs like WHM. SCH/SGE is a bit more of an argument...
I'm a bit confused what you mean by damage ceiling being closer without people complaining. I thought the point of making healer rotations more busy was so that people who are bored could be less bored, not to push people who enjoy simpler rotations out of being competitive/raise the skill ceiling? Which is it? The first I'm willing to support, the second I'm not. If people are just going to complain that someone has an easier time, then we might as well stick with what we have now as we don't have to worry about THOSE complaints with the present system - which is how we ended up with it in the first place.
Besides which, there already IS some WHM optimization, people just tend not to get it.
Yeah, a bit of nuance isn't bad. But as I say, if we give players that with 3 Jobs, why must we with all 4? Especially if 1-2 of said Jobs are going to be a good bit more complex than they are now?
