A new form of URF.
Since Riot won't bring the Original URF back, i thought of a nnew form of URF. How about you try to combine URF with One for all Mirror Mode (since we didn't get that one either for I think 3 - 4 years?)
Mode Name: One for all URF (Mirror Matchup) Map: Howling Abyss
I know that you also stated that you can't bring O4A back because of Client HUD issues or something in that way. But atleast try to do such a mode if O4A is working again. Release the mode on the PBE so that people may test such a thing and if it works, you could try to officaly release it on Snowdown, because its a cool gamemode.
