Why League should be balanced for challenger/master

Imagine you join a chess League. You start playing and win some games. You get up to maybe their gold division. Now, you run into some complications competing. People in gold are utilizing their complex pieces like Knights and Bishops way better than you, while are more use to linear tactics like your Rook(Castles) and Pawn Cheese. On top of that, the chess from gold and up has timed moves.

Would it be fair, for you to demand that Knights and Bishops be removed, replaced with linear Rooks(Castles), and the timers to be removed? Just because you cannot think on your feet, make moves quickly and utilize complex pieces. Doesn't mean Master tier chess players should remove Knights and Bishops and stop castling, remove the timers and have a slow and linear game. Rather, you should have to learn to play chess better, faster and with more skill in order to compete with them.

This is a thoughtline I never understood. "We should balance the game for the majority." If you balance for a majority of people, who are low skill level, you set the bar low. If you start removing all of the complex mechanics from the game and fast moving twitchy champions, and replacing their kits with slow linear ones. You are shitting on top tier play, for the sake of what? Making sure low tier plays get a participation trophy?

If the game was balanced around the most middle ground in League, Silver, that means any player above silver has an imbalanced game, and in order to have a balanced game they have to play the game worse. If you balance and design the game around Challenger/Master tier play however, that means when the game is played at it's most optimum, it is balanced. And low tier players will eventually adapt and to the best of their ability try to mimic them, achieving 'balance' by getting better at the game.

Currently, League tries to balance for everyone, the problem with this is, it means it is balanced for nobody.

Yi is OP until gold then worthless above. Riven is worthless below gold then OP in Diamond-Challenger. This is no way to balance a game or a sport.

So before you condemn complex pieces, advanced strategies and timers. Think to yourself. "Maybe I just need to get better at chess. Instead of trying to tear master chess players down to the level of my Rook and Pawn cheese." Because the moment Riot balances the game AND designs for top tier play? Every champion becomes a viable pick when played to an optimum level.
