Say what about nova bomb? It's underpowered and underused so no nerfs needed, it needs buffs if anything. Positioning matters with the nova bomb, it doesn't with BB. With nova bomb you have to be sure you'll kill the target cause you've got 1 shot and 1 projectile and you could kill yourself in the process. BB you get 1 shot, 2 volleys and like 20 knives per volley. It's hard to miss with it really... It's got far less drawbacks than either nova bomb.
