Stuck between 25 - 30 normal wins, no progress in days, ready to give up climbing for good

Your post doesn't make sense.

But I made a post awhile back, some people may disagree. If you are hardstuck in bronze, give up on climbing. It is very hard to do, to just not care. But you only have 5 months to get to Gold. It is possible, but if you couldn't climb to high bronze in the first 5 months, getting to Gold will be in even tougher. There is nothing wrong with being bronze. If you are doing well and having fun games, then there is no problem. You can still work to improve micro and macro, can learn new champs (since you gave up on climbing).

Hopefully by not caring about rank, you will have FUN playing a game. And maybe you will get better, maybe you won't. But if the game is stressing you out, it isn't worth playing. And the chances of getting those gold rewards are just super low.

Alternative is a brand new account. But to get that to 30 will take awhile. Then new champs, new runes.
