not yet, but i've dced from using ugly bomb, broadside, sometimes easton, RF, and other skills, but maybe it's a problem with skills in general (only this class?)
it's so frustrating after waiting so long to use these skills aahh
It looks like Quickdraw really is the cause of it. I chose not to put any points into it due to seeing this thread and I can use all my skills without a problem.
EDIT: jk I just d/ced once when I used my ugly bomb.
