It's possible i've missed it. Sometimes i accidently click on the alerts when I'm not ready to read them, so I miss them.
I'm willing to do it, if you want to double up. It's where you play, for example, your prefered character whom you want to be paired with X, a character I'd like you to play to be paired with y, and then i'd play x and y
Oh of course, I know what doubling is love haha. I'm open to playing as Clark, Chato/El Diablo, Robin, The Joker, or if you're into FxF: Harley, Ivy, Diana/WW, Raven or Starfire
