So many animations are so rigid and/or too acrobatic.
MCH is so weird jumping all the time, it feels like it never takes a hold of its gun.
DRK running animation feels like you are dragging your weight across the battlefield, instead of dragging your sword.
The DRG/SCH/SMN/WHM running animations feel so stiff.
In short, I wish that at this point, and for the next xpac, they would rework some jobs' animations, especially for old classes. They've done a good job with GNB/DNC.
