You might as well be combining Tier 1, 2 and tier 3 heavy hitters together if you want it to even have enough players to ever have a competition, including inactive players who could come back at anytime and still dominate the other tournaments.

Could also make it anyone in the top 50 in ladder are eligible to compete in TOC tournaments, and anyone with 3000+ wins, but if your name is on the official list you are not eligible to compete in the other tournaments. (Just to try to help fill out the brackets for these) because even with a group this big, chances of having these guys logged on at same time are slim, and I am sure you want to have at least 4 or more playing at once in these or whats the point.
Then winning x amount (I think 2 or 3 would be a good number) of the lower tier tournaments can earn you a spot in TOC.
Also would suggest the prizes for TOC being slightly higher at least to add to the importance of it.
