I just saw the lol-dominion. As it is a game mode, I suggest to merge it to the game it refers to : league-of-legends.
I do not think we have cod4-ffa or other like that for each type of game.
(Or maybe we should make game-modes tags like ctf, ffa, ... ?)
There were only 8 questions, and I don't see the harm, so merge performed.
