Why Dominion should NOT be removed from the game
There is an entire community built around the map dominion, thousands of people play hide and go seek on that map in custom games. By removing the dominion map from the game permanently Riot will be destroying that community and game mode that is loved by many league of legends players. Riot needs to keep that map in the game because there are far too many people that enjoy that game mode and that is the only map you can play it on. Maybe if Riot were to add a better custom game creator, that made it so you could edit minion spawns, turret placement, etc..., then it might be acceptable but until this happens-which it probably never will- Riot should keep the Crystal Scar at least available for custom games.
