This is pretty cool, I was playing this last night.
Its not just a random hack and slash MMORPG, its a MMORPGRTS, you get two teams, human and monsters, you build up your resources etc, one person on your team (You can take turns) acts as the RTS dude, building stuff to enhanced the team and making workers, they can also tell players what to do, but you don't have to obey, so you build up your stuff with the buildings etc. (Like units you can play as an weapons and items) and train until you're ready to attack your opponent, I like being the behemoth, but everybody sees you as a huge threat and gang up on you.
