True, if I host it's no rules unless survival then carpet level 3 (as I think that's a bit op for survival - but it can still be dealt with, I still join survival games that have no rules as well.)
It is difficult to get people to believe that a 2v2v2 can be played without rules and without 100 SCUD Storms being built in a few minutes; And if you do get one going people will complain that they are losing because it is no rules and not because you are actually bashing them.
If only people all played 2v2v2 without rules, then the games wouldn't go so long and would be very exiting at times with the added chaos.
