All for One (One for All Alternative)

Dear Riot, I have a simple question that I hope you can answer. On the Rotating Game Mode, I've seen most of your old game modes come back and this has made me very happy. However I've noticed two game modes have not made a return, and I was hoping you'd fill me in on if they are coming back. The first one, and the one this question is titled, is what I've called All for One, the alternative version of One for all, where both teams select and vote a champion on Howling Abyss, then both teams play the same champion on both sides. I remember playing this and having lots of fun, and I'm hoping to see it return. The other game mode is Doom Bots, the hard but fun game mode where players were put against super powered bots and could only claim victory if they did their best. I hope to hear from you soon about these two amazing game modes. Your friend, Shaen.

Also, PS, I wasn't sure whether to post this hear in gameplay, or if it should be in feedback or something. If it's in the wrong place, feel free to move it as you see fit. Thanks.
