As above, Spear's problem in raids was that people tend to pick up a very specific cooldown rotation. For example in O4S, you could throw all the cooldown reduction at me that you wanted, I simply wouldn't use it as pretty much everything is set in stone.

As far as changes I'd like to see:

AST: Fix the damn button bloat on cards already.

WHM: Some means to generate Lilies from DPS, a 100% rate from Stone 3 would likely be excessive, but as much as I hate RNG, 30% or so would work well in this case IMO.

SCH: MP values for Adlo and Succor would go a long way, I also still think that Bane's nerf should be reverted for SCH TBH.
