Thanks for the replies guys I'm glad it's been thought about!

And you're right Valkyrie, people do complain a lot :P I didn't mean to be too pessimistic, I just thought it was a cool suggestion.

I remember when SB expansion came out - lots of people were really positive. But I also saw a lot of complaints about things that were just petty :P
"Ugh my class is ruined" etc etc :P

I think this is constructive criticism, though
