On Dominion's Removal
I'm going to get downvoted so hard for this, but...
I've been playing League since before Dominion came out. I was there when it launched, a brand new exciting gamemode with different mechanics, new styles of play, all the shiny bells and whistles. It was the latest, the greatest thing. Riot promoted it heavily and supported it on par with Summoner's Rift. And it was popular and well-liked.
For about a month.
Riot stopped supporting Dominion because a very large part of the playerbase abandoned it, not the other way around. It didn't make sense to devote the level of time and attention that Dominion required when it had a tiny fraction of the players that SR did and couldn't even muster up numbers near what Twisted Treeline or ARAM have while it was being promoted. Even with a large number of bot accounts inflating those numbers. It's always sad to see a gamemode go, but this shouldn't come as a surprise to anyone. The only thing surprising me about this decision is why it didn't happen years ago when it was clear that Dominion was never going to be popular enough to warrant the support it needed.
There will be a lot of angry threads, a lot of protests raised, but a lot of those will not be from people who played Dominion as a game mode regularly. They will be from people who played the game mode once or twice, consider themselves 'a Dominion player' because of it, and are simply looking for reasons to hate on Riot. Were Riot to go back on their decision now and leave Dominion in, it would not get any more popular - Many of those who protested its removal wouldn't play it because they never played it anyway and won't start now. Even if they updated it, fixed it, made it better. Us veterans, we've been down this road before and we know where it leads.
I feel sorry for those who did legitimately play and enjoy the game mode as well as for those who used the map in creative ways, such as for 'hide and seek' custom games. RIP Dominion. You will be missed, but we didn't need Clairvoyance to see this coming.
