If you’ve ever played any of the melee professions and/or weapon styles and perform a lot of dodge rolls while fighting, there’s a good chance that you’ve experienced a bug that’s been in Guild Wars 2 for a quite a while now. The bug happens during certain chain auto-attacks of melee weapons and will sometimes cause a dodge to fail. It seems to be most easily reproduced using slower weapons such as the Guardian and Warrior Hammer and Greatsword, although Thieves, Rangers, and even Mesmers can also be affected by the bug.
So, what happens? If you hit dodge at the precise moment when the cast bar for a chain attack is firing off, you may find that the dodge animation and movement displacement doesn’t happen, but you still lose Endurance. For a good write-up of what weapons cause the bug, check out this thread on the official forums. And for those who have experienced the bug, ArenaNet has some good news! The team has finally found a potential fix for the issue and plans on implementing it during the next full game update. Here’s the dev quote:
