Combat will be what kills this game [end of days! redeem! blah blah!]

It will look awfully retarded to have animations be cut off halfway and start another one just to be cut off again.
Your character will look like he/she is having an epileptic fit - Immersion much?

Get a mnk to lvl 50 for dragon kick. The animation is ~3 seconds long and it gets cut off every time I do a skill as soon as GCD is finished. Is it epileptic and weird looking? Dunno, I don't notice it because I don't pay attention to the animations. I prefer to pay attention to things that will keep me alive like avoiding bad things or my threat, or making sure I am doing all my abilities correctly to ensure I am doing max dps. Maybe if more people did that as opposed to watching at the beautiful animations, people would play better thus making everyone's life more enjoyable in the game. Truth be told, I would prefer it if the animations were something simple like a punch or a kick or a flip and that's it for the move. No need for fancy 3 second long animations. As for the off gcd abilities, they need to make those instant and have instant effect just as the op suggests. Trying to stun a 2.5 sec cast with a warrior is really tough when the animation takes 2 seconds and the stun doesn't go off until the animation is finished.
