Is it possible to carry yourself from bronze to gold with any role?
Realistically is it possible to climb effectively up by getting very good at whichever role is your favourite, regardless of the meta, FoTM, etc?
In Season 4 I climbed from B5 to S1 with Twitch, I like adc and I prefer to play it, but I'm considering putting my effort into getting good at jg or top to get out of low mmr.
