Goodbye Dominion hello Magma Chamber?

A long while ago Riot decided to cancel Magma Chamber. If my memory serves it was because we already had the extra maps/gametypes of Shadow Isles/3v3, Howling Abyss/ARAM, and Crystal Scar/Dominion. I've played LoL for 3 years now (I originally was here in season 1, but left and didn't come back until season 3 where I make my time-stamp of officially starting), I remember how beautiful Magma Chamber looked back when they had the LCS players have some matches on it. 1v1 & 2v2 are things players have been heavily requesting. Now that Crystal Scar/Dominion is being retired, why not finally give us Magma Chamber/1v1&2v2? It's a map/gametype that at the very least will be just as popular as ARAM if not more popular. I understand the entire splitting the playerbase deal and how it will slow down the queue times, but honestly it won't be that huge of an impact because players will still play the other modes. On a side note I will miss Crystal Scar/Dominion in my own way. It was what caught my eye making me want to play LoL years ago when it was 1st played by LCS players (I think, it was a long time ago). I remember watching videos online one day and randomly seen a commentated match of Dominion, it was really exciting for me to watch back then with the energy of the commentators. Without Dominion I probably never would have been interested in the game to begin with. So while I rarely ever played it, I will miss Dominion.
