This is an addition to the rooted/stunned bug that prevents you from moving normally.
If you dodge and animation cancel by swapping weapons and holding W, you can retain your dodge speed.
- Is this a bug or an exploit: Both.
- (if a bug) How did the issue effect your gameplay: You go fast
You can fix this with a relog.
