I have decent win rates, but can never ever win promos on the first attempt, it takes at least 3 attempts. so climbing is super slow. I'm playing Zilean a lot at the moment to if you play kai'sa, Vayne, twitch it is great, if not it works with most.
I'm from the UK, am salty as %%%% but never flame. Don't often hard tilt and can bring myself back. pref voice coms and a friendly duo.
