Wait what. Inferno isn't that bad. I picked it on accident...
The worst part about it is not having enough ammo for the shotguns and them being easily dodged (don't have to dodge to dodge them so have to make sure you have a head on angle to someone, like shooting their side while they're strafing someone else)
It just sucks when you're vs a lot of melee and don't have a pinaka. But if you do have a pinaka it seems like it should destroy melees.
