@L4T3NCY URF and ARURF
Posting this here since I don't have PBE acc (and this is my NA acc, I'm EUNE main).
You "justified" the delay to bring back URF and make into ARAM by "getting stale too quickly, same champs... etc". So, ARURF came and totally ruined the mode.
Fun modes aren't supposed to be 'healthy' or 'balanced' or anything like that. Fun is something totally subjective. I for example may wanna spam Jayce in URF to go fire at will level 2 after getting too tilted from normal/ranked. I saw many people being frustrated for the change and rightfully; you did something without asking anyone's opinion and totally ruined something so great as URF.
By the nature of this mode, not all champs are good for it-like all the special modes. For example, yeah, Garen can keep spinning non stop but that is no good vs a full poke and cc heavy team. End result is, most games leave you with a negative experience in a mode that supposedly is for fun. Since you have no control of what you'll play. That's why I avoid modes like One for All and Nemesis Draft. Don't make me ditch URF too- or make a 'special URF only account' with only the champs I wanna play there (I think many are considering this).
In the very least, you could do the following: make 2 separate queues. One with good-old, well-known and beloved URF and one with this (censorship) ARURF and see which gets played the most. You did that with Doom Bots recently so you can't go with "2 queues is too heavy". Unless you know already which way the overwhelming majority will go thus revealing ARURF for what it is.. a !@#$%^&*
