Speaking of stealing japanese ideas has any english webslopper done a non retarded version of pic's central premise?

The MC is isekai'd to a game world and gets the "weakest" class which is actually a centerpiece of one of the most OP minmax builds and uses his game knowledge to break shit over his knee. Except the author barely knows what he's doing and doesn't manage to write any convincing synergies or builds.
The whole secret ultimate build turns out to just be "uhh the shitty 0 damage class has a self-shield. the op synergy is just get the berserker skill tree that gives you more damage at low hp and then put up the shield so even though you're 1 hp you don't instantly die. that's it that's the whole secret trick". and it barely makes a difference because everything he fights breaks the shield in 1 hit anyway so he ends up just nohitting the bosses at 1hp the same way anyone on any other class would if they bought the same berserker skill book
