Rito pls... Finish Magma Chamber
Since Dominion is gone and the game mode variety feels small, finishing Magma Chamber makes sense. Having Howling Abyss is nice for 1v1 and 2v2 matchups but the map layout makes for limited gameplay and strategy. I think finishing the map and adding some kind of objective other than towers would be a great answer to this problem. The potential the map showed at Season 3 All Stars was huge. Make it with the same rules as then, but as I said with an objective. Make 1 and 2 man queues with 3 bans and blind pick. I think it would get a lot more love than Dominion and would be a great alternative to ARAM and the classic 5v5.
