Alot of the animation differances you mentioned are an illusion. Sabo charge for instance..it looks like it takes longer because of travel time,but it lands before the global cooldown is up,so really it takes no longer than the other. Sorc also jumps in the air and lands when they do knock back. Thy actually jump up and do a flip before landing. The only one that seems iffy to me is Project. i like the spell animation tho,I think it's awesome. Someone tried to tell me the damage is applied instantly when you cast Project,but I disagree,I never see the enemy health bar move until the projectile actually hits them. Maybe give Sorc animation a slight delay to even it out? /shrug
I know i'm rambling,I'm tired a nd not proof reading. =P
