I've played as several different archetypes on several different servers, and pretty well convinced myself that I should play on one of the more populous servers (Freedom or Virtue, looks like) since I play at lower-traffic times of day, and I have set to see any server look genuinely overcrowded.
If anybody actually plays regularly, and their play-times might reasonably intersect mine (Thursday evenings and Saturday mornings, mostly), let me know what server you're on. I have a couple of characters I wouldn't mind keeping, but nothing so compelling that I couldn't restart. I've mostly been trying out different archetypes and figuring out what I enjoy, but haven't put very many hours on any character but one. And he's a hero on Pinnacle, so I may not put too many hours on him anyway...
It'd be nice to find a SuperGroup (the CoX equivalent of a Guild) with people I know and like. I haven't done much of that in online games. Failing that, it'd be nice to adopt or start one.
So if you've got an argument about what server I should play on, especially an argument of the form "I play with a group I like on the <Hero/Villain> side on this server so you should join us", this is the time and place :-) Let me know!
