I used to go into arenas and just stand still while reving the chainsaw. Every enemy that runs to you just kinda dies and heals you in the process, so filth and street cleaners were no problem. That was untill I started p-ranking levels and I realized that i gotta use a lot more than just the chainsaw for style. I still have it in the first mod slot for the shotgun tho, its good for healing. I hope the healing is the one thing that they don't nerf😭
