i really hope riot brings back dominion for the costume play so we could play hide & seek. it was really really fun, and i'm sure a lot of people agree with me. it would be even better if they would make it into a game mod so people can't cheat. for example; make the seekers without an HP bar, so they can't be killed. or that when it gets to 40 minutes they seekers auto' surrender (same for hiders if they all have 5 deaths. we all had those hiders that lost but then just won in a 5v2.) and not just a RGM. but permanently.
tl;dr, please riot. give us back hide & seek.
