S9 ranked start -- game is out of balance IMO

I've been playing LOL since S1 and right now the ranked games are so out of balance. Tanks are out of control and really raping and ADC's barely do any damage if they are just a bit shut down early. It seems if one champ gets just a little bit fed early game they are snowballing out of control and you can't counter as the games are to short. In the old days you had more game time to work a come back -- now games are over in like 20-25 mins. And if your team fails to put a tank on the team against two enemy tanks late game is GG. I usually can tell at 10 mins if it's GG -- and I've been accurate about 98% of the time in predicting the outcome of my ranked games. Support champs aren't even supporting anymore -- traditional supports are not able to do much against all the bot lanes running things like brand or mage support who goes full damage. Riot you have to figure out balance and quickly please -- tanks and tank items are too OP. Champs like Garen, Voli, Malphite, Xin, Darius are just broken. This is my opinion. I'm not saying I'm a great player but I love this game and I've watched it change a lot. Ranked right now is just frustrating as hell in solo/duo Q. Thanks for listening and I hope to see some balance tweaking happen very soon.
