Here's what I don't get about the U.R.F. and Rotating Game Queue.

Why can't we have both? And when I say both, I am not just saying urf and Rotating Game Queue, I mean ALL game modes and Rotating Game Queue. Why can't riot give us our traditional game modes for their two weeks alongside the rotating get queue. For example, during Christmas time they stop with the rotating game queue for 2 full weeks of Legends of the poro king, or sometime through the year they stop with the rotating game queue for 2 full weeks of ascension. I am not here to bash Riot for not bringing out urf, but removing the 2 weeks for a featured gamemodes in favor of getting it for 3 days every 2 months when they can do both seems kinda stupid.
