I actually prefer 3vs1 taunt parties the most. It's fun to gang up one the crasher. It gets boring sometimes in 4 person taunt parties, but that's why I have hacks. But the darn randomizer never picks my stage and when it finally does, usually one of them has left by then. Ever notice how there's always this one mean taunter who doesn't act nice all the time, has anger management problems, etc, and can ruin it sometimes? Anyways, whenever there is a 3vs1, I try to stay peaceful, taunt/couch from the sidelines, avoid stealing kills, and join in if things get hairy. The reason I do is because I don't want some jerk to disconnect in the middle of the battle. I've had that happen WAY too many times. <_<
Still, if one person is dumb enough to disconnect before I bring in hacked stages, well, they deserve not to see them. Also, if the crasher is a noob, then I bother them by Infinite chain grabbing them for every battle possible until he/she leaves if the others catch on and don't ruin it. But seriously, every time I try to infinite CG, there always some taunter who just wants some action and tries to beat up the victim even if it means saving them and possibly even killing me. But, if I don't feel like taunting, want to battle, and there is only one guy taunting, I'll either taunt with him, or continue fighting, but avoid hurting the person and protect him. If there are two taunters, 3vs1 time.
