Yea I often do the same as Insetick. But as soon as there is another person, a taunt party is inevitable. Although it is true that many taunters truly want to fight, i wouldn't be surprised if many start taunt parties for nothing other than to team up on someone.
Whats frustrating at times is when someone is completely oblivious to a team effort. Two people who are "taunters" won't touch each other teaming up on the other two, and the guy i'm with is just too stunned to realize whats happening. Most often these people are very much in the newb category, and don't really recognize the group dynamic which is all too apparent to me. But i guess a stunned out newb is better than a taunter who will just join the team.
Overall tho it is quite sad how badly overrun basic brawl is by taunt parties. Worse part is that it is a bit of a self-fulfilling prophecy. As i'm sure there are countless people who get the game, go try out the wifi, meet a taunt party, get 3v1'd and then never bother with it again. I think this is the biggest shame of taunt parties is that they are so alienating. "But its just for the lulz" is a pile of BS, its little more than inane behaviour by sad people who think they are special or elite cause they can hyrule jump using PSI magnet, or glide indefinitely using MK or some other pointless display of "skill".
Wifi may be horrible on this game and taunt parties just make it worse. Which makes this one of the few threads which might actually improve Wifi.
