so you guys think Beta 3 will be good for clans in leagues and such?
Absolutely, with the introduction of round based gameplay, full support for team modes, and custom LUA gameplays you can do whatever you want to setup your tournament.
I will be including tournament esque features at some point such as wait time BEFORE a round starts, all ready, shit like that. Although i don't think it will be a priority until right before release since thats going to be copied right from HL2's code (its buried in the SDK)
