As far as I know, Iron Banner allows all advantages from gear and even levels. So it's most likely a 20s only or prepare to be wrecked.

Damn - so that is an "endgame" type of thing. Like why even think about heading into the iron banner until you're level 20? I hope that's not the way they do it.

That's what I understand. I know that going in at lvl 5 in beta, I got absolutely slaughtered by the 8s.
