Hello,
I had experienced this bug since Gw2 launch, it does not happen often but it is still there to this day. What happens is: My character while initiating running/walking freezes as I press W. Releasing W or clicking other keys will break this animation freeze. I suspect it has to do with animation/physics of character legs but I cannot confirm it. But it looks like my character legs get stuck when running animation is just about to begin.
Its not serious bug but major annoyance when it happens, specially during PvP where I want to get distance or run my character gets stuck (freezes) and I have to release W key and tap again to activate running.
No, it is not spell like cripple ect. Because it happens sometimes when I just run around exploring.
No, I do not hold 2 or more keys down while it happens, sometimes it just freezes my toon as soon as I hit move forward key.
If anyone knows whats causing it (if on my end) then please let me know.
