I have to agree with the masters should be in their own tier (or at the very least, I am not in the correct tier at all). A quick look at the people in my "tier" tells me that some of them may be at a disadvantage against me. Don't get me wrong, I like winning probably more than the other guy. But, I'd rather win in a fair match, and I'm not sure pitting me with my 1000+ rounds up against the players in my tier is fair for those players.
Plus, my scoring average at the time of the tiers being created was not exactly accurate. Give me another day of playing some ranked rounds, and then rank me according to my average at that time as my average will be more indicative of my current scoring level.
