I am to team reliant

I am extremely useless as Ahri when my team is loosing. I believe this is a mage general problem right now. There is to much going against us. Resolve tree gives supports 50-100~ average hp around lv 4-5 which is extremely bad against mages, if they go bonplating they sucessfully survive all combos from a lux ahri, velkoz orianna with easy in the early game despite the level difference, just because we can not make up for that extreme HP increase in DAMAGE. It doesn't matter if Ludens echo's price got reduced by 100gold or rabadons scaling got increased by 5% if they get 100extra hp early game, that meanst we need to find nowadays on average 150extra magic damage which we simply do not FIND. In the end it leads us being extremely teamreliant, almost never being able to oneshot suppossed "weak early laners" and not allowing us to snowball/carry the game. The reason zed talon and all those assassins are played is because others like orianna lux can not snowball. And no it doesn't matter if u are suppossed to afk farm mid, when the game has changed so hard that proactivity in the early game is #1 reason to win a game by a mile. You can not turn around a game with tilted teammates that are 0/4 and even if u are by some magician wonder good in the midgame due to Powerfarming your enemys will simply go or to completely counter your hard work that you did the entire game. my peak elo was diamond 2, before the adc's got changed, i played the entire Season long at Diamond 3 Elo, and right now i've falled down to platinum 2 MMR. I can not turn around the game, my kda is 3.5 average much higher than it was previous ( 7.2 / 4.4 / 7.4 of my last 20games keep in mind only 35% games were won) feel like my class has lost it's final last tiny carry Potential of the game, it's actually ridiculous at this point i need Dfg back so much freaking tanky have supports/adc's become in the early game due to changes.

Does even someone of you on the balance team play a mage? How has this not being noticed by you other "diamonds" yet. I am sure someone on the balance team should have noticed this by a long time now, if he is really playing in Diamond Elo, that despite all the "mini dmg buffs to mage" they actually deal LESS compared to before now Fix this immediately i am starting to loose my mind
