Nah, I'm fine for now, hitman, blops 2 and planetside are going to take up most of my time... And I'm not very "into" the whole starcraft multiplayer scene....
Any active players around? Keen to practice 1v1s, I'm platinum protoss. Haven't been playing for long, wana get good before HOTS :P

Its a full game in its own right, pretty much like every other "expansion" these days. People are happy to pay $60 for Mass Effect 1,2&3 or Call of Medal of Creed Wars (tm) 1-101 etc etc. It's a franchise market and its a the best way for any gaming company to make cash, so they can develop more games for us to play in the future.
I think the only mistake Blizzard is making though, is by having the restrictive WoL requirement.
