I recently bought the devil you don't Its a decent hand cannon if you're accurate. Without any form of accuracy, until you receive the perfect balance perk, you might as well keep it in the vault. I recommend handing in bounties to grind XP for the hand cannon until you get perfect balance. With the perk you should do well. Also Whoever said they use the Devil you don't for crota I cannot imagine it being of any use whatsoever except for maybe the first checkpoint. Even then, its best to use a scout rifle. i recently got the Fang of Ir Yut. Phenomenal weapon.
