I'm not happy how teams can preset themselves in a manner that allows "new" accounts to lock with a "high" account and go into team games. It brings the higher rated player into matches against players they normally wouldn't be setup against. Inevitably the "new" accounts DO NOT play at the level that they are supposedly at either. So it makes for a very one-sided match as the normal account/ranks just get steamrolled by the vastly superior high ranked player and the suspiciously good low ranked accounts.
It's not fair, it's not fun and it very much smacks of rank manipulation. This isn't just randoms doing it either- spikeynoob has done it repeatedly as well as a number of other high profile players. It makes it so that I don't want to play in the ladder because i know some ultra pro is going to just stomp my entire team without thinking while i'm barely able to perform basic functions in the game as it is.
