My personal experience with the animation delays has been 100% tied to deflection animations playing at the same time. Simply put, I want to use Ability A, but my character is busy deflecting a blaster bolt, so it takes a second or two more until the ability actually starts. This problem has only been present when I play melee. I only have two characters; one Assassin tank (who obviously deflects a lot), and one Sorcerer (who rarely deflects). Two ends of the spectrum. As I said already, my Assassin has a lot of delay in activation, but my Sorc has almost none. It seems to me that they could fix this problem mostly by retooling the way that deflections (or any automatic animation) is handled, but allow activated animations to have priority over automatic animations.
