Climbing on support (solo)

Hello guys.

I am currently P2 on the EUW server, and i'd like to learn stuff about how to play support, or how to actually carry on it.

I'd like to learn about laning, midgame and lategame aswell. I will read every comment, but i prefer to take advice from high elo players, can post OP.GG

I play 3 roles on an okay level but i intend to improve, so here i am.
