I was b3 at the end of season 5. Then I did promos and I had an afk every match and went 2/10........ Now I carry almost every match and I still lose. I main ADC so there is only so much I can do when my team initiates without me and leaves me in a 1v5. Some one look at my stats and give me pointers or tell me what im doing wrong Thanks
Korillo3 votesFor one, your vayne build is terrible. 
and 
are not good items on vayne. You could perhaps make an argument for phantom dancer, but drop from your build and never think of it again when playing vayne.
You also have an insane amount of deaths. In the last 7 vayne games you've played, you average 9.29 deaths. Some of these games you have a lot of kills, but dying so many times suggests that you are prioritizing kills too highly, and probably making trades - which often is not the right decision.
In your last 20 games you have never, not even a single time, purchased a pink ward. Not a single one. Nor have you ever bought a blue trinket (and as an adc main this amazes me). The blue trinket is incredibly useful for an adc, and never buying a pink ward suggests that place little to no importance on ward control - which also suggests you have poor map awareness (along with your high number of deaths), so these are likely things you can work on.
Your cs/minute is quite low, which goes along with the theory that you prioritize kills to highly. Try focusing more on farm and objectives and less on kills.
Ronker2 votesWhy do you want to leave Bronze? Crazy talk man...stop it.... Sit back and enjoy the wonders of Bronze
Catloaf1 votesYour are NOT carrying. You have 10+ deaths almost everygame so it doesnt matter that u also have 15 kills. If you wanna get out of bronze you must go 20 0 everygame but if you cant do that then you dont deserve to get higher. #BRONZEISEASY
Poptart Evelynn1 votesItemization and skill order are poorly optimized.
Normal start
First B
First complete item
Then from there base it on the events of the game but most people go infinity edge next.
With vayne you need to be maximizing utilization of her W. Max W first.
Stop getting W first and E second. Start your roll first.
Stop getting Hurricane and PD on Vayne. It's not that good compared to other choices. Rapid first is amazing on her.

delonix1 votesA lot of my advice has already been given, but I figure it wouldn't hurt to hear it again from somebody else.
You shouldn't think that you "carry almost every match." If you did carry so often, you would be winning more. You probably need to adjust your definition of "carrying." To you, it might mean having a lot more kills than deaths, which you seem able to do. That doesn't win games. You main ADC, which means you should be focusing on getting objectives, killing enemies in teamfights, and staying alive. If you spend time chasing down a kill when you could have done a bunch of damage to a tower, you aren't carrying, you are throwing. If you don't want your team to fight without you, tell them not to fight while you splitpush or recall and join them.
Do some research. Learn what items do, what your abilities do, and what items work well on which champions. I'm not as opposed to phantom dancer on Vayne as other people seem to be, but you are making questionable decisions when buying items in at least some of your games. You should also no longer rush 
. It's better to get +
and then finish IE.
Your CS is low. Low CS means it takes you longer to buy items, which means you do less damage to objectives and less damage to enemy champions.

Raide1 votesThanks for the info peeps I'll let you know how I do as I start focusing cs not kills and looking over my builds I realize I can do better and I shouldn't blame my team for a large majority of my losses also I'm in the habit of haphazardly warding so I'll get that sht straightened out haha
