Well,being C'thun kinda sux...i couldn't really go anywhere,i couldn't get any girls...it'd be a pain in the ass,especially the part where I have to deal with dumb groups trying to kill me every 25 minutes.
Being Ragnaros,well,i couldn't hit the swimming pool,and i would probably have to hang out at the Molten Core all day long,which is pretty boring.But at least i could walk around,and smack my minions with teh hammer for being lazy.It still sucks though.
No wonder the Old Gods are represented as a pissed off bunch.
