I know for a fact that HoA hosts AW, DAoW, TSoL, and a few other RTS's.
We are also working on the next version of AW and DAoW. (i personally am part of it)
it is called HOA-AW on azeroth and northrend.
Same with our rival clan LHoT.
They basically threw in a ton of random things with no regard to balance, but they are more up to date if u can call it that. o.0
