I feel like when patch 6.9 happens, I'm done with this game.

I've pretty much always been a support main. It's always been easily my best, in fact, I'd say I was a natural at it that did quite well even the first time I ever tried the role. It felt like the game was reasonably balanced then, and that some champions weren't some absurd amount stronger than I was. But that's going to change, in a really bad way. The support role is already by far the least liked, and it's getting some substantial nerfs in this patch. Less MP5 on the frostfang line and lower health restore on the relic shield line. Not only that, a significant loss of global gold from outer turrets and of global experience from inner turrets means supports will be even further behind in both gold and experience. And they're significantly buffing grevious wounds, which is another support nerf in disguise since almost every non-self-heal is done by a support anyways. And I hear they're also nerfing Soraka way into the ground and nerfed Taric, too, but didn't seem to buff any supports. Oh and they also made the red and blue buffs juicier targets or something like that, which is another buff to champions that aren't supports since supports rarely ever get the red or blue buff. Not only that, but every AP mid that will be any good will likely rush some crazy new Hextech Protobelt -01 which gives tons of stats and mobility + 75-150 + 35% AP extra damage to multiple targets as well. This would make most mids that rushed it be able to pretty much zone a support out of even doing anything in too many fights since someone like LeBlanc could just instakill you with 3 dashes + a flash, allowing them to have bigger zone control of you than the fight even is.

These really hurt supports where they're weak, especially the less gold + experience garbage, and quite possibly could make support players become so rare that people can barely even play games in dynamic queue anymore. So I don't want to switch to another role since after these changes, other roles would probably have like an hour queue times. I feel like it'll make the game not even worth playing to me. Is there something I'm missing that gives this any hope or is the game just ruined because no one will ever want to support anymore?

Alternatively, Riot still does have a chance to change my opinion if they make some balance changes to fix this before that patch goes live. Surely I'd hope they'd listen because of they treat their support mains badly enough, they could just all abandon this game. Riot don't let this happen or you'll ruin the game.
