Guild Wars 2

Sometimes when I am using the longbow andrenaline skill my character does the animation, but no projectile follows, the skill goes on cooldown, though the andrenaline stays.

Same thing happens at times when using Arcin Arrow – no projectile or damage, goes on cooldown, and my character does his animation.

maybe you cancel the skill just before animation finishes?
for example, you use arcing arrow but just before the animations ends you try to dodge and accidently cancel the skill

Nope, havent dodged at all – I think it might be related to LOS, not entirely sure though, but its certainly not dodge or any other form for cancellation atleast.

I’ve noticed this as well. It’s obnoxious. On a side note, it would also be nice while using the adrenaline skill, that if I choose to use it at a premature stage that it doesn’t cancel because it advances to the next stage.
