I don't think bans are necessary, if so a good chunk of the people who have beat it would be gone. I for one only get to raid with players I meet on the forums, most of my friends quit playing so if I'm in a fire team that wants to cheese I'm not going to beg them not to because I'll get kicked most likely and then I'll have to come back to the forums find a new group and odds are they are cheesing to. Just let bungie fix it like they did the loot cave/atheon/Templar
