You don't know how much you will miss something until it's gone

I'm talking of course, about Dominion.

The reason Riot is getting rid of it is because the effort to maintain or update it was simply not worth it for the insignificant amount of people playing the mode.

If more people had shown interest in the mode it wouldn't be going anywhere; or rather, it would probably even get a full visual overhaul.

It's a bit late to show interest now. Please keep this in mind for the other modes; if you don't want them to become a low priority or even removed, you'll need to play on them. It's basically your vote for where Riot puts their resources.

Hop on Howling Abyss (ARAM) and Twisted Treeline (3v3) occasionally if you want to support them.
