Does riot even care about what most of people want ?

i dont really understand why is riot making desicions that almost no one really likes : elise changes azir nerfs ( we dont know if sure o.O ? ) zed nerf karma rework ? people want from riot to change abit riven yet still nothing interesting happend to riven that ulti speed is not really a big deal. Riot have done so many things that people dont really like ? why not ask people and look their opinions before doing something ? this game u made is to make fun for the players but yet you dont seem to listen to them at all people wanted kassa buffs where is the kassa buffs ?? whats next you are going to do for this community so they quit lol ? nerf the most popularted and balanced champs from each role to the ground ? pls make me communication with the players before making decisions
