This is fantastic suggestion! Not the solo part, I'm thinking that's impossible. But doing this as a team. So what kind of team do we think it would take to do this? All Defender, Controller, or Corruptor teams could probably manage it.
So let's take it a step further, no repeating AT or powersets. What does everyone think would be a good team for such a challenge? Rad, Kin, and Cold buff/debuffs are the ones that immediately come mind. Time would be good here as well.
My initial thinking is Blasters, Stalkers, and probably Scrappers might struggle more than most. Brute and Tank would be good for this. Doms are pretty squishy too, but the extra controls would be nice.
