Many complaints have been made that there is little community aspect to the game, and I agree. The biggest problem is that there's no REASON to interact with other players other than getting together for a Heroic, Flashpoint, or Operation.
I'm not really sure what the solution is. I hate to use SWG as an example, but players did t least have a reason to go to the cantina and hang out awhile.
Anyone else got any good social ideas?
