I like them both but they are very very different. I absolutely love the character creation part of COH and have spent many hours making my characters pretty. The level of detail in WoW seems far higher than CoH and CoH is definately more grinding.
I'd love to have our WoW people play CoH now and again though, it does feel diiferent from WoW. It would be a nice break just to have Zel, Neo myself etc on TS trying (probably poorly) to be a bunch of superheroes.
I mean - can you imagine the design concepts these people would come up with!!
For WoW people it would be very therapeautic. We can be silly, everything is very spectacular and glamorous and the fights are soooo easy (oooh did I type that out loud!!). None of this balancing party rubbish - you can even run away now how easy is that!!
You can fly and teleport and shoot fire out you hands yaaaaaayyyyy - I'm in......
