I think no one (at least me) is arguing to balance for competition only, but to low level should have a limit.
It is impossible to balance for all level players and it shouldn’t consider the players who don’t know the concept of the game, which what I saw from replay or stream those 1400 elo are sometimes not having right concept but just trying to keep the OP build.
This will just create trouble like Sweden was almost unbeatable level at the beginning still had people to say they were weak, also at the same time some people were saying Sweden just fine in the competitive level (I don’t know it really was or not due to I am not competitive player).
That’s why balance should not be only for competition and also should not consider all level without bottom limit, from my opinion.
This is reason I prefer showing data than just showing own opinion.
You are top 1, you think A is OP, how if 2rd thinks A is UP but B is OP? Data is the only thing can tell the truth.
