Guild Wars 2

it happens sometimes. it could be called ‘ok its not that big of a deal’ but till you fix imparing disruption this buggy behaviour is going to give me a stroke all the time.

And what exactly is the bug supposed to be?

And what exactly is the bug supposed to be?

the first part of the flanking strike ability is an evade. As you see here a randomly timed interrupt can still cancel it regardless, making you vulnerable for the next second + proccing impacting disruption. basicly if this happens duel is lost.
no idea if this happens due to server lag or it’s a bug but needs to look at.

PS: updated first post with second video

The evade on it simply isn’t instant. It happens with pretty much every evade skill in the game that has a cast time.
