For me it doesn't change much anyway, i prefer to play in the higher only tourney bracket, because the games are more challenging. I won't "purposly not play low rated players" because i'm not to bothered if there are lower rated players in the tourney. And as for teh "protection" of my higher rating.. tis a load of cobblers LOL, i've played people of high or low ratings since i joined the site, and it has still remained reletively high.
