It's a very weird system, have you guys noticed for example if you're hit by an ability or not is depend on where you were standing at the end of the cast finishing, and then damage is applied at the end of the cast animation? So if you stood in a spell with a very long cast animation you'd still be hit by it no matter how far you run. On the other hand it's possible to walk back into attack animations as long as you were out of the effect once the cast bar finishes. I'm not sure if I have a problem or not with the way LB works, it feels like you have to be very careful when you're about to use it which can be a good thing.
