@Awhoo_Thunder I rather not see ranked control unless they fully delete Arenas. Simply put having 7 "modes" (duos, trios, trio ranked, arenas, arenas ranked, control, and control ranked), is too many modes to split people across and I doubt that many people are going to want to grind 3 different rank modes, or a combination of them. The main modes have a lot of players, while arenas seems to have only like 5% of the game's playerbase playing it (don't know exact numbers, just that you see diamond-preds in bronze-plat matches because they don't really have anyone to fight).
Not to mention the fact that they need a better anticheat. I just got done playing 4 matches of control, and saw 3-5 players on the enemy team, with 2-3 that I've noticed on my own team (when we fought near each other) using aimbot and what appears to be wall hacks.
If they can solve the hacking issue (or actually detect people cheating more often than not), narrow down the modes, amonst fix issues like audio, servers, etc. and do something about the smurphs, then the game should have a larger community to eventually support 3 main modes and 3 ranked modes.
Currently I don't see that being a thing.
