I'm going to say it: Regular URF beats ARURF hands down
I don't know who thought URF got dull... it always had fast queues the entire time.
ARURF can be fun some games, and garbage other games.
In regular URF odds are at least 3 people on each team are picking strong champions that they know how to play.
In ARURF it seems more often than not, 2 or 3 people get something OP that they know, and they stomp to the tune of 20+ kills against people on not-strong champions that they don't know.
URF was much better. If people really needed to play their not-strong champion in URF, you could have made a separate queue for that (and then you'd really see how many people would prefer URF).
But w/e. URF itself is still fun and it's worth sitting through 2-3 garbage games to get that 1 good one. 4 ADCs versus Alistar, Jax and Fiora was sure fun though...
