I see your point, but how would you ever do 5v5 until the new demigods are put in?
I faced 3 regulus' once in a 3v3 match, and it was pure ownage with coordination, while probably not impossible to counter, you'd have to do it with the right setup, they waited until we all selected ready then quickly swapped to reggy's. I didn't complain or anything, just tried to adapt to it and we made a stand, but eventually lost.
