Why was Dominion removed?
This game severely lacks content, why bother to remove any of what little extra content exists?
Summoners Rift doesn't really work for competitive gameplay anyways cause this game has become too streamlined for such a small map. Went from being slower paced with very specialized characters, and few highly mobile characters (Kassadin, Nidalee) to just a mosh pitt of power creeped, lightning fast, all-in-one super battle droids. Everybody nukes, jumps, and basically does the same thing. Jump at a target and throw your keyboard at them. The map is too small and lacks intricacy for these terminators.
Dominion was perfect if I ever wanted to come back to this game on the occasion. Why bother removing something you put time and resources in to create? I could understand not creating any new maps or game modes, but why remove Dominion instead of just leaving it alone and never updating it?
