Whoa a whole three people? Aw shit. No, no bans. This doesn't effect anything at all. People getting great faster has no impact on anyone else other than emotionally. Mathis is something that can be patched and will be. If you ban all the people that did this, it would probably be around the majority of Crota kills which is a lot of people. Not in Bungies best interest. Fix it and move on.
