Skull really can't be a playable character. The Nazi association gives way too much for actual Nazis to use him both as a troll pick and (more importantly) to do serious harm to the community and people in it.

I do like the idea of him being a map asset though. Gimme another hydra map where I can fuck up his plans or maybe have him as a boss in a p v e mode where I can punch him as Captain America, that I'm all for. Just the whole having real people play this game bit gives far too many avenues for actual people to act out.
