PC if you aren't using a controller in crucible, you are at a huge disadvantage.

If you’re using KBM, just use a hand cannon like Better Devils- if you’re accurate, it’s basically has scout rifle range and the damage drop off is minimal. It’s essentially a 3
hit kill if you’re able to hit the head twice.

I use an elite controller and feel like I get my ass handed to me by everyone using hand cannons. Hand cannons are more accurate using a mouse and keyboard.

If you are blind and play destiny you are at a huge disadvantage.

Controller and mouse and keyboard on d2 is pretty balanced both offer advantages and disadvantages way less recoil and precise aiming balances aim assist

So i am a mouseplayer. Had my cousin over. Hes playing in xbone. We pkugged in the controller at the pc. He was as good, if not better than me.
i get a kd from 2 sometimes with mouse he got a 3.33 with controller.
so i guess its just a matter of choice and own preference
Only disandvantage i could notivlce was that he couldnt 180 his vow as fast as me with mouse
