Cant climb Bronze I-Silver V

Hi everybody,

So im playing league since 1year and a half, and after a 6w/4l at placement matches, i dropped into bronze II, was actually easy to climb against bronze III/bronze IV. Now that i am bronze I, have to play with Silver V players, and i just cant handle this anymore.

I do everything i can, i generally win my lane, or if i dont i try to be as useull as possible in fights, thats what every bronze player would say right ? But here's the problem, maybe ican win 1v1s, but it looks like win and lose depends of picks and bans at this elo.

I have like 90% loserate with a vayne in my team, those silver V players usually act like if they were pro cuz they escaped from bronze, and always try to play hard champions, and when they pick vayne in my team, i just lose.

Or the first pick that wont listen to their team, they just ban champions they cant deal With, without listening to their team's choice, i had a garen first pick, i said to ban darius, cuz ennemy would pick 100% sure, he acted like he didnt see what we said. And well, darius did a penta this game.

I can even make a list of champs you have to dodge when they're in your team like : thresh ( too hard for our lvl) Vayne ( still didnt see a lvl5 vayne carrying a game, they just throw ) Darius ( in ennemy team ) Lee sin ( too hard for us ) Teemo and shaco, ppl playing these champs are just guys that want to do like youtubers " TROLL TIPS TEEMO OP XD LOL" but they fuck up the game.

Or i dropped into a cho gath jungle olaf support game, i dodged, better lose 3lp than seeing this. And i will not talk about teemo adc, and a shitty game i did with shyv ( yet that was my fault if i lost, i sucked )

BUT HERE IS THE THING, i had tese teams, but i can get te ennemies team aswell, i got teams that carried so hard, i could even afk, we would still win cuz my team was so good. And after doig all these ranked, i really think bronze I to silver IV, its just all about luck, if youget the team or not, if the bans are good or not, its not even skill now, i did pretty great on wu jung, but thresh had to take 3 of my kills, leblanc fed hard, and i wont talk about garen.

So im just asking you guys, how can I win in those 1v9 situation, when they dont listen to the rest of the team, ban stupid champs and dont read the patchnote ( i saw a few bans of darius skarner and garen, better ban nasus they say ).

PS : i tried duoQ, and I can say that, i get the mosts stupid champs in my team when i duoq, i have more wins in solo.
