To Climb from Bronze: Spilt for Towers
To climb from Bronze, it seems to me that the team that can push their lane to the base tower before other lanes finish win games. To that end, the supports that take towers quickest seem to hold the biggest advantage. ADCs are going to be better than most other classes. And since there are two of you, bot should determine the lane.
So which supports are going to be most effective at advancing the lane?
Sorry if this sounds like alchemy. I've been reviewing my games played and I can't find a solution to getting out of Bronze.

Is ok. Even when I beat him in lane in bronze, he would still get first inhib if I stop pushing top.
Should be easy enough for a few bronze games.
and
, they just chunk the towers with in the 5-6 min for 1st turret if left alone with turret.
