So im currently stuck at B1. I figured out it's not my teams fault (even tho there are a lot of trolls) but I simply can't carry games. I can't make much diffrence with my current champs.Do you have an advice which champion to buy so i can progress in game.Maybe I should learn other lanes as well?
Top: Simply shit at it
Mid :

Jungle: Totally bad and I only have like 
ADC: Simply not my kind of thing.
Support:

Thanks :)
10cs a minute should be your goal, pick malz and abuse hitting an E on them and then just before it stops reset it with the silence.
Its hard to help without watching the game, but general things like always having a pink on the map and spam pinging danger when you see the enemy jg helps.
I think it's as much your team's fault as yours. Them being bad makes your margin of error nearly zero, and you're bronze, so youll make a mistake eventually. Try to make zero mistakes.
man easiest thing to get outta bronze is just win teamfights , bronzies sux at team fights , so if you know who to focus and how to teamfight as ur main champs then its a free win you can single handly win your teamfights as viktor( he is absolutely sooo strong)
