Just because YOU were bored of URF didn't mean everyone else was - and vice versa
So please, just give us both urf and arurf and let queue times tell you which one the players prefer.
There was a lot of hate on the boards over how URF got stale, and there was a meta, etc... Riot has echoed those sentiments as well.
Yet the last time URF was out in full glory, every queue i had popped in under 2 seconds. Despite it having been out before and for 2 weeks straight. Even ARURF queues didn't pop that fast its first time around. Blood Moon queues took several minutes at times even though it had never been out before.
I personally enjoyed URF. I don't play many different champions, i like try-harding in normals so i can't even go there and try something new. Yet with URF i felt comfortable picking anything deemed OP because everyone did it and even if you fed no one cared as long as they were getting kills (and if they weren't too they were happy to let the game end asap rather than have to sit around while you carried them). URF was a good opportunity to just play for fun rather than to win.
ARURF may seem the same, but it isn't. There's a level of frustration playing a champion you aren't prepared to play when someone on the other team has an OP pick that he's good on.
Also, i believe the biggest problem is that unlike ARAM where people will trade a strong pick if they're not good on it, everyone that plays ARURF wants the strong pick for themselves. No one will trade me Hecarim (who i destroyed URF with and have mastery 6 on) because they know he's strong in the mode, even if they've not played him and end up feeding with him. Likewise I'm unlikely to give up nidalee even though I've never played her in my life. Then on top of that if i do roll hecarim, it seemed to happen fairly often that people would ask for trades then dodge if i didn't (out of spite - if they can't have the op pick i can't either). All-in-all it really wasn't nearly as good in my opinion.
Which doesn't mean I'm right or you're right. We're both right because it's our opinions. I just don't resonate with riot's argument for switching to ARURF and i think it'd make a lot more sense to see what the players prefer by releasing both together and seeing which queue gets more action. I'm willing to go with the common opinion even if I'm wrong - if ARURF truly is the preference then so be it. So ARURF supporters (riot included) - are you willing to, or are you just scared that URF is truly more popular and want to put your preference over the majority?
If what you claim is true you lose nothing. If it's false then the players get what they want. It's a win-win.
