I miss the quick, easy-going, casual friendly teams and PUGs.
Teaming just worked so well within CoX.. As long as the leader was on top of grabbing new missions it was nearly non-stop action, hopefully with lots of witty and friendly banter in the team chat box. When one tries to team in most other MMO's you spend all your time trying to sync up quests, having to deal with obtaining even more "Bear asses" since everyone needs their own, and worry more about level gaps (Why isn't something like the side kick/Exemp system more broadly implemented in other games? It's bloody genius!)..
CoH teams also had the added advantage of being easy to fill/easy to leave. If something came up and you had to hope off, no problem. Your team should get along just fine without you, so you don't feel much guilt in leaving.. Not like some other game's I've played where if a certain player throws in the towel the entire team is dysfunctional without them...
I'm finding other MMO's just a drag to play anymore.. No one teams, and if they do its through a group finder in a dungeon, which turns out to be a loot run.. End result being a rushed, super fast run, no one talks, they might as well be bots.
Then I also miss Defenders/Corruptors.. Hot-damn, they were support on steroids. Anyone who complained about those classes probably never played a WHM in FFXI, or a support class in pretty much any other MMO hehe..
