I mean it clearly states in the news article that One for All is being removed on 12/2, but I've heard different, and that it will always be available in custom. I just need clarification.
Freezman1 votesI heard that they are planning to have rotating modes. And the reason they can't have all of them at once is server load. But I don't remember where I heard it so it's a pain to find a source, I may have even heard it in a chatroom so no "evidence".
VexingRaven1 votesOne would think if server load is preventing you from adding the game modes you'd like and keeping them, you would upgrade the server cluster. Then again, we are talking about Riot here, their logic has always been a bit fuzzy.
StrayState1 votesI did hear that they were rotating official playlist like Freezman said, though I believe they did say that the newer playlist will remain available in custom game types. I'm not sure on the specific source though, perhaps it was an earlier Reddit?
