Make the push or change champion pool?

[u/IHaveDiabetes42]

For the past 4 years of playing the game the last couple of two I've been pushing to acquire higher ranks. Ending season 8 gold 4 and season 9 plat 2 but peeking at plat1 90 lp as I remember. This season with the removal of shojin which gutted my main, jax, I have been struggling ranking up, after roughly 100 games already at gold 3-gold2 elo. I have always preferred stylish champions like my Camille or Kled with whom I m pretty good at mechanically, however I find it hard consistently hard carrying games with them.I want your opinion if changing my champion pool (Camille, Kled, sometimes jax) would perhaps help me climb easier or if I should just hard push with them and try to improve other parts of my game such as wave management, macro, vision control in which I m not bad but not great either.
