Okay, so. I believe that One Man Army should work mostly as it does, but have its description edited to be clearer that it only cares about what other players there are, and only be available on a single character. That way you can have a 'main character' and then a supporting cast, if you're into that kind of thing.
I also agree that there should be some kind of separate level one talent for being a solo character.
And I think that this discussion is pleasant, and hopefully people can continue being civil in it!
