To wit: took a CoH character from 6 to 16, all on Winter Lords.
Seriously, this event was messed up. Atlas was a ghetto of level 30-50 heroes flying around and stomping WLs while the youngbloods ran around trying to scrap together a couple XPs out of it. And don't get me started on how hard it was to get on a team with a controller or tank. Terrible failure.
Well, terrible failure except that I got o powerlevel a couple characters. But Still.
