It's as simple as the RNG System. It just sucks, that's about it.
Edit: Let me explain before the down vote squad arrives. So I feel as though in ARAM, one team is designed to loose or that's how it feels. So in the end it depends less on skill and more on team comp. ARURF is no different.
Edit: Also it's not fun having to wait like 5 games to get a champ that's semi decent to play on urf or 10 games to get that champ that's amazing.
This Is Your Dad4 votesI recommend having urf where you have to play a new champion every time to a limit of ten games, so you are forced to play a variety while still having some choice in what you play.
FlameanatorX1 votesI feel like a better version of your idea is to limit the champion pool each game randomly to ~40 champions, most OP ones get banned. That would force even more variety, rather than simply rotating through 10 strongest non perma-banned champions.
This Is Your Dad1 votesNot everyone even owns 40 champions.
FlameanatorX1 votesNo I mean of the overall champion pool for all players in champion select. So whatever champions you do or don't own, you can only play the 40 that were randomly selected for this URF champion select (minus the 10 blind bans).
The Leo Cat3 votesWhy would anyone downvote a demand for normal URF? The ARURF is basically who ever gets the champions that can abuse the hell out of cooldowns better wins.
While normal URF is virtually the same, it lets players choose their favorite champions.
AR URF1 votesWell the demand for URF is trending, but I think people down vote based on the person behind whatever thread it is to keep things divided. it seems strange, but that's how I look at it.
FlameanatorX1 votesPeople downvote because they think AR URF is fun. It's that simple. While I certainly would enjoy regular URF coming back once in a while (such as the next time an URF mode is available), I think AR URF is an overall better mode for just having fun.
Killer30001892 votesI love both URFs but it's nice not going against the same 10-15 champs every game. 
are just a couple xD

Play full AP amumu. It's legit can stop EVERY single FoTM urf champ.
Due to the combo of having massive burst and 2 stuns one if which is a big aoe that doesn't even need to be targeted.

With 10 bans i'm sure you won't be seeing much of 
and the ones you just listed.

Hmm... it seems like we have a problem. There are much more than 10 overtuned URF champions. :P Personally, I don't care that much and would still spam URF games if it came back, but this is part of the reason that many people like AR URF more.
FlameanatorX1 votesHard to land that first stun on most of the champions he showed. Trollpoll, perma-super-speed, invis-flash, multiple dashes+untargetability, etc.

Ahhh. That's because people try to land Q first.
Save your Q and simply press R when they get into range. Then your 100% guarreenteed to hit your Q and E.
The range of the R is such that only nid can reasonably stay out of it's range and still kill you. And at that range it's simple to just walk away from her dodging spears till flash is up.
deoje2992 votesI just want regular URF with the 10 ban system, this would solve the problem of the terrible champions no one likes to play against as well as the RNG.
AR URF2 votesI only got to try urf once and loved it. ARURF is complete garbage.
FlameanatorX1 votesPeople keep saying this, but I experienced significant agency in most of my victories and losses in AR URF. Yes, some were basically pre-decided, but even those were still sometimes fun for me, and they were certainly less than half the time.
The thing I really loved in AR URF is that so many more champions felt strong in a toned down power level environment. In other words, if you're not just constantly getting nuked from stealth by or having to deal with the insane mobility + dmg of etc. or being chunked from across the map every 2 seconds by 
, then a lot more champions become semi or fully "viable."
Ralanr1 votesThough having a meta in urf sucks more imo.
Rand0mH3r0X1 votesThe reason for rotating game modes is so that Riot doesn't have to balance them.
You're issuing complaints of a problem for ARURF. Those issues won't, and should not be addressed.
ARAM gets balancing done for the mode, but not towards the champions, as was the case once with Dominion.
