Riot Strike is supposed to be insta cast, but it doesn't actually interrupt till it's done it's animation. How does this make sense?
There are a number of abilities like this, they don't actually work until the animation is complete, and this is completely seperate from the fact that sometimes you can't even use your abilities because you are in the middle of one animation or an other.
I mean yeah when you're pve'ing it's pretty cool to see the animations SOMETIMES, but I am tried of hitting abilities in both pve and pvp and having to spam the key because it's not working due to some animation.
