Put Dominion on rotation like URF or One-For-All instead of trashing it!
Exactly as in the title. Why completely remove Dominion, when you can put it on rotation, like URF, Snowdown, One-For-All and the other game modes? This way it will definitely see more play (which will finally give Riot a reason to bugfix the map - wasn't lack of play the reason?). Also, Riot won't lose customers since there are a lot that only played Dominion.
I - for one - enjoy Dominion, but got annoyed when I encountered bugs a few times. But seriously, Riot. Consider keeping it on rotation - I don't wanna lose a fun game mode.
