You can't make an omelette without breaking eggs, I'm sure Riot isn't trying to mess with your champion poll personally. I don't think Riot goes into your games and see what champions you play personally and say " NERF HIS ......... Graves. " or what have you. They hear someone say " GRAVES is too op and they see 20,000 other people say it also they then nerf the champion and its bound to get others upset about it( like you).
" I'm seriously considering not even playing anymore" - Don't do that dude nothing will stay the same with the balancing everything-everyday- Every champion-items EVERYTHING is getting Nerf, tweak- balanced so don't take it so personally.
If its not fun or you do quit no one is stopping you in doing it. Do you think random people in solo Q will go " getitcrackin quit the other day heard he stood up to the Evil Empire called.... RITO lets pay Respect to the Great Getitcrakin". No one will sorry but your not important enough for riot to only listen to you. (ONLY)
Does riot care about you ...... Y.E.S they do but do they care enough to just not nerf the champions that you play and you alone and only hear your own voice of reason not listen to the other billions of people .... N.O
" Your killing the gaming vibe. Get your stuff together "
Maybe you need to get it together cause they don't need to get nothing together, does Riot make mistakes HELL YEAH they do but they try to fix them god forbid it upsets you in the process.
What Vibe are you talking about? The vibe is what you make it to be if riot is nerfing the champions that you play give it some time and don't play those champions for a while play different champions.
Sorry for your luck with the Champion nerfs etc.
Have a Good One !
