A friend of mine just dinged 80 again the other day, and it put him into a community that we joked about: the "one-of-every-class" club
. Like a few of our readers (including William B, who emailed us a while back), he now has ten 80s, one of every single class in the game. It's not something I'd ever do, or ever want to do, but certainly there are probably quite a few people out there who've gone all the way to the highest level with every single class.
would say, it definitely gives you a nice overview of how all the classes work and what their strengths and issues are. And of course it'd be handy to run instances with -- you can roll into endgame instances playing whatever role you want
or your guild needs to have.
