I've got to agree on Goodbox's point, that it's something people should expect. Since Toribash is a competitive fighting game, and the main goal for the majority of players is to score a high rank or win something.
Now the boring thing is, they want to do this the easiest way possible (logical of course), which is... Dum, di dum.... RUSH MOVES AND/OR RUNNING AWAY!
It's super effective against new players, and totally ruins their mood and motivation. I've played wushu and lenshu since late 09 when I first started Toribash. And I know, it is daaaamn annoying. The reason as to why it is annoying is because...
~ It ruins the feeling of accomplishing something for new players. While the other player has increased chance of winning, and is having fun because he most likely will win. If the opponent is unexperienced or unsuspecting.
~ It totally ruins the replay.
~ For people trying to have a good time, and actually want to play fair, it's fairly annoying when that one guy (I.e. me123ster, for those who remember him) uses 1 single move, all the time to increase rank and earn tc.
There's nothing wrong with them of course, they're just simple. Egocentric.
Might be useless to discuss, since people have free will and making rules against it would be silly... But it's true.
