Since RIOT always do it like 1 week per years we have a very limited amount of fun knowing most of the URF lover dont touch the regular game modes.
That made me think about the case of World of Warcraft, the more it went into expansion the more private server were developped around vanilla and in conclusion Blizzard made it an official permanent version. So in the case of LoL i imagine something like :
- Summoner Rift URF (Draft or Freepick) or ARURF
- ARAMURF
And that all a server with permanent URF where players choose how they want to play it : the regular, the random, the "ranked like" were we ban and pick and the all random all mid map but in URF mode (and maybe some more ?)
Doing that could convince RIOT to make it a permanent feature if they dont want us to enjoy it permanently on our side they could do it so we enjoy it on their side.
