I do, and I've completed a few, but the bounties tend to be rather technical, or you need rank 2 for the class item to complete them. They do not follow everyone's play style, which is almost necessary in a competitive multiplayer. You want to finish the bounty, so you have to play with a weapon or item you're not used to playing with, but on the other hand, you want to play with what you're used to so you can play your best competitively and have a chance to win. Limiting weapons for bounties is ok for PVE because there's no competition, and there's no unique reward for winning. PVP, not so much.
