So, this is my profile: https://eune.op.gg/summoner/userName=maayonmaayan .
I was climbing well and good , reaching Silver 1 easily and lost two times (1-3 and 0-3) my promos to Gold 4 and after that I am pretty much on decline. Though I am improving (vision, map awareness, kill participation) imo, I am probably going to demote to Silver 3 soon. Though I am not worried about rank and demoting, it kind of kills the fun and demotivating to play ranked games itself.
While I do write comments on how unfair matchmaking is or how hard it is to climb as supp or how bad adc players are in my elo, I am (maybe) failing to see what mistakes I make (as we all do) and so I want some support specific advice and is boosting the only way to climb?
