Listen to this carefully, it is not the art-sound or casting time field for those who dont no what they r talking about. Go to avatar ability, and look at "animation name" or something similar to that, it should be the first or second field. The reason bloodlust has that time is because it orders the unit to perform a specific animation which takes time. If u remove the animation field or set it to something else less time consuming the casting time will go away. This also depends on the caster of the ability, which can be fixed with changing "art - casting point" and art - casting backswing" in the unit editor of the caster.
