Of course comes the big question: once the game returns; how many will you recreate? The favorites? The powerhouses? All of them?
Or create a few then wait for CoH 1.5?
I've had a lot of time both during and after CoH's run to ponder what worked (for me) and what didn't. By the end, I was playing Controllers almost exclusively, and, as my preferred roles were:
A) Locking down groups with Holds and Slows
B) Confusing enemies rather than fighting them myself, or loosing pets on them if I needed to
C) Stealthing ahead to the end of the mission whenever I could possibly get away with it
My final most optimal choice (for me) was an Illusion/Time Controller. The absolute best stealth in the game (go look up Stealth for a comparison chart on ParagonWiki), lots of long distance Holds and Slows, a Confuse available, and 2x pets (Phantom Army and Phantasm). Since the shutdown, I've tweaked it in Mids, and even gotten some help here on the Character Optimization boards to make my last build even more efficient.
So at present, I'm primarily interested in picking up where I left off, though I've toyed with builds for a Fortunata and a Mind Dominator as well.
