This game is not for beginners like how PGR, Honkai, Aether or any of those were designed to be. It was already stated long before in the articles that this game is for high spec devices, in case you missed it. "Gacha is abyssal" ? "as Netmarble usually have" ? Netmarble is million times more generous than any of the companies that developed those crap which make you go through hell before you can finally obtain a character of your desire. Gacha drop rates in Solo Leveling is average, but be grateful they give away tons of free gacha tickets & currencies as well even though the game is not globally released yet. Can you name one ARPG which had the wish list option right from the very beginning? Not just characters, even the SSR items there are not too hard to acquire either.

Nah, high end devices are not needed. Chipsets with a gaming nano score of 30+ can handle the game fine. Netmarble will optimize the game further.
