He is right though. I always had fun playing Jon Solo style as well. The one thing I missed is not being able to see the dungeons. You really need friends or a guild to see those. My grouping experiences to go through the few dungeons that I did enter were somewhat dismal. I really wish they would implement a way to go through them by yourself.
The Warhammer game does look pretty cool! I wish I could give it a shot, too bad there's no OS X support or I probably would. Initial online reports seem interesting. I'd totally play a Squig Herder.
