I am, but I've only seen one or two others. If you have IM in Omega, how effective are you finding him to be? Was the trial hard for you? Have you changed your build for Omega? What equipment set(s) are you trying to put together?
For me IM is doing fairly well, I can't say I've had any real problems clearing Omega content with him. I did change my build a little, bumping up my defensive stats, but I'm not sure it's made too much of a difference compared to my other characters who are still running with minimal build space given over to defense. I play an Energy build but I've swapped out Repulsor Spray for Micro Missiles because the short range of RS was causing me more problems than it was worth.
Iron Man was my third character to pass the Omega trial, after Hawkeye and Ice Man, and I was surprised that he was the easiest and I passed it in one try.
I'm currently working on the Blessings of Blackagar Boltagon set but not having much luck. I'm wearing 2 pieces and have a couple more stashed that have really bad stats on them.
