you should be able to make some progress if you belong higher tier than you are now
It's a nice pretty theory that most people like to tell themselves. But below a certain ELO, it's a lie.
Also, there is a hidden assumption in "belong". Some people like to recursively define "belong" as essentially, "if you cant claw your way up there, you dont belong there".
However, if you put objective numbers and criteria on, lets say, "belonging to silver".. you can find that someone who fits all those criteria, still cannot climb up from bronze to there.
proof of this:
I have 2 accounts. One I started years ago. One is new.
on the old one, I'm stuck in bronze 5.
on the new one, while I havent finished my promos yet... in normal draft mode, I consistently get matched with silvers.
(and I may get placed directly into silver5 or something when I finish my placements. We shall see)
I have a good kda, reasonable cs, and know how to get objectives. I have good map awareness, AND WARD.
So, my new account clearly demonstrates that I belong in silver.
Yet if you only look at my old account, your theories would claim I belong in bronze 5. because I cant get out by myself.
So, your theories are wrong.
in bronze 5, there are only a few things that will get you out:
- luck in matching
- having a really good duo partner
- learning how to be a kill-hog, super-carry, and carry the whole team (yi/garen, anyone?)
This is a different skillset from simply being good at your champ and lane.
