Not to be rude but if you really are good, you wont be in B5 even if it was your team... i have tons of Silver accounts because i know how to carry in bronze. Plus, you seem like a person who will flame with his team mate... that's bad. 3rd, the champions that you play isnt great NOT BECAUSE of the meta... but because there kits doesnt support much on the role you pick. Think of why it is called support.... this isnt Dota were even supports hurt like the carry or acceptable to intentionally KS or CS. Nope. Anyway.... I main support when I was bronze.. now im ADC main so i understand how support works for a long time... my supports are Janna, soraka, thresh, alistar, annie, zyra, karma, blitz, braum, leona. I already see alot of wrong things in you but yea, just keep playing and you'll know how the game works and which champs work better for the role
