I don't GAF what people pick as long as its 222, if its not, fuck off with your Hanzo or Mei.  I had 2 memorable matches this weekend:  First one I was doing something else so when the screen comes up I instalock zen because he's usually fine everywhere.  This was eichenwalde defense.  I come back 30 seconds later and we have: Rein, Winston, Sym, Bastion, Genji.  Yeah.  And yet we held A somehow.  wut?  and it wasn't a matchmaking eff up, we barely got A ourselves on attack with a much better comp.  Who knows.
Other one I was playing Ana on KOTH, we have a super mouthy (text chat) Pharah complaining about not getting heals.  Dude I can't magically find you when you're off doing your thing.  Finally on match point in round 4 or 5 I say "cool you want heals, you can play a healer this round" and take Pharah after he switches off of him.  Of course he doesn't switch and we lose.  Not sure what I could have done there to win that game I guess some times you just are gonna lose in those situations.
