1. Entrance points higher (A LOT HIGHER, like 30.000-40.000, not 2.500!)
2. Only ONE alt per player
3. 10 games top with each other player (2 days of comp)
4. 2 game related vio's (or notes) during the round and you're out (like now, not sure if notes count)
5. A dedicated mod team (a task force for the round reports)

There would certainly be less ALTS playing (the number of players wouldn't vary), but the QUALITY would rise A LOT.
