One thing I really loved in CoH were themed teams. All weather, all cold, all fire or whatever. I've lead or played on teams with LOTS of different themes. I'm hoping to do so again in CoT.
Since we don't have specifics on the ATs yet, use the best CoH equivalent for now.
What kind of themed teams would you like to play in and why?
My two favorites are the Common Origin (we were all hit by the same bomb, all Mutants, all on the same irradiated spacecraft or whatever) and the Common Power Theme (all Rad, all Fire etc). The former is good for setting up small but active SGs with a few tight friends for scheduled play. The latter is good for Theme Nights or superteams trying to see if they can take on all challenges. Either one allows for a variety of ATs (for that time when you REALLY need a Tank) but still provides a common hook.
I remember when Star Wars was cool...a long, long time ago...
