The April Fools Joke
I think everyone should get a cigar except Graves, and when I say everyone, I mean EVERYONE. Every minion, every monster, every champion model and splash, every critter summoned (i.e. Yorick's mist walkers, or Malzahar's Voidlings), and everyone summoned by ultimates. Can you imagine how hilarious that would be?
EDIT: As far as I know, no one wanted to censor the cigar, Riot just thought they might. Plus McCree has a cigar in all regions so it shouldn't be an issue.
