"The community" is much larger than the small, very vocal group that is on the boards. Personally I'd ignore most posts that say things like "everyone hates it" and "the community" in this sort of tone if I worked at Riot.
Riot is moving toward being teamwork focused, and the people on the boards here are mostly resisting. The change is coming whether people like it or not. You just need to learn how to work with strangers, rather than doing what "solo queue" was.
It's not punishing anyone, or ignoring current interests, it's changing the game to go down a different path. They do that to some extent every year, and this year is the largest change to date.
I'll never be able to play my bruisers and off tanks from season 2 again, but I don't obsess over it either. I absolutely loved playing them that version of the game is long gone. There are no legacy servers for league, and that's likely to be the case forever.
Just remember, change is good.
