While I like there being some sort of incentive or "trophy" (doesn't have to be an actual trophy but something to show off) for the top teams, I wouldn't mind them changing the nature of the reward. For example, I think it'd be really cool if SE took the top 4 teams on each Datacenter and streamed a tournament where maybe the winning team got something special (and the other 3 teams could get a participation award as well). Of course they'd need to implement some sort of team registration system... but the point is the reward would be more just getting the opportunity to play on an official SE stream which might have 100+ viewers instead of some virtual item that someone else will be willing and able to cheat to obtain.
