The problem is that GA is the optimal gamemode for a lot of players. Quick games, full hero selection, smaller areas of play and most importantly, It's PURE pvp (no additional bots like in Supremacy). Sure, people want modes to escape the "full PvP experience", but Supremacy isn't really a "full PvP" experience and it feels a lot less competitive than GA.
We understand CS, Co-op and HvV are very popular. Nobody is saying they aren't and we wouldn't want those hidden away either. We just want GA to be one of the "main" gamemodes, even if it gets less content. As I and many have said, relatively smaller regions struggle a lot with the smaller gamemodes. I could queue up all day every day for Starfighter Assault in Australia and never find a game. Hiding GA, one of the biggest modes in Australia WILL hurt the playerbase numbers and make queues harder than they already are.

...don't want it gone.
GA isn't going anywhere, we're still confident it'll be played and enjoyed by those that want to play it.
