Not that I totally agreed with the changes I do at least see why they made a majority of them.

-Nerfed CC abilities should be a given, because some classes got jipped in that selection and others (mainly BRD) had too many of the good ones. It basically just leveled the playing field in the CC ability department.

-Thunder for Blizzard II, well this is kind of give or take. DoM's are complaining because their single target DPS takes a hit without it, the plus side is DoM jobs like SMN and SCH actually get a half decent AoE to use.

-Holy Nerf Well it has more potency than any BLM spell, costs less mp than most of their spells, and stuns for 5 seconds bit of a no brainer there.

-MNK and DRG both got boosted so I don't really know why DRG's complaining, they can use their jumps with less consequence now their flanking bonuses got boosted by 5%, some abilities got boosted in potency and duration and recast timers went down on some abilities.

Other than that alot of the changes made sense if you think about it, but then again I can't speak for everyone.use.
