Why Rotating ARURF is healthier than URF in the long run

It is more worthwhile to improve the problems of ARURF, as it already solves many of the problems of regular URF.

Urf's fun comes largely from the ridiculousness of the situation, and the sudden upsets that occur throughout the game. Everything feels less structured, and champions function very differently in exciting ways.

When this mode is consistent and available, a meta develops. People figure out which champions are strong and which ones to pick together in which positions to make the game more winnable. Urf then becomes regular summoner's rift with different champions in different roles. When Urf is random though, you can't pick the same champions every game. When Urf is rotating, it is less worthwhile to tailor your account toward it like one may do for ARAM. It would be better to preserve the randomness of Urf and try to level out the power level between champions than to simply give up everything ARURF has gained.
