I think it's either split community, or "fuck off" to duelers.
I don't see how champions can integrate fairly into duel. I mean only way for this to be fair if both players are playing same champion. Which kills the purpose of champions, therefore they should be disabled in duel.
I imagine there are a number of ways to try and balance champions in duel. Only a subset being available on different maps, ban/pick variant, modified charge time for active ability, same champions must be used in one match (a set of 3-5 maps) etc.

But anyway, so far ID's announcements are pretty inconsistent. And whole PR seems pretty scrappy.
