Boards/reddit make up such a small portion of the community. I think almost no matter what they do to this game it's going to remain popular for a long, long time. I've seen people say that "the game will die soon" since season 4. Old veteran players that find the game stale will eventually funnel out and be replaced by new players that don't think it's stale since they've only just started playing.
I think Riot knows this too which is why they may not even listen to boards feedback about their ranked plans.
Sucks but I think that's the reality.
