The stats in this LitRPG are Attack, Defense, Accuracy, Magic, Recovery and Evasion.
Those are IMO trashy stats from some B-tier computer RPG.
Because it's "Attack" instead of "Strength", you can ignore Attack if you're not a damage dealer, and still carry a heavy backpack with your normal human strength.
It's "Accuracy" instead of "Dexterity" or "Perception", so it only affects ranged weaponry. Thus, it's just a stat point tax for archers.
Similary, "Recovery" doesn't give you HP regen, it just makes you better at divine magic specifically.
So yeah, the standard in this kingdom is to put most your points into your Class' "main stat", put some in Defense if you're a melee class to make sure you survive a hit, and have all the rest at 1.
The MC, getting a Priest Class, starts with high Recovery and puts a bunch of points into Evasion, and is shunned for this, because healing is weak-ass unless you put all your points in Recovery.
But with 50 in Evasion, he is unhittable.
...Which is just bad game design. The only reason the MC has an interesting build is because heroes get probably ten times the starting stat points, so he can afford a quirky build.
And Evasion is a God Stat, so it works on nearly everything, nearly every time, and when he doesn't, he can cast Shield on himself.
In this setting, Boss Rooms are not even locked until you defeat the Boss, so this guy just strolls through the Boss Room, casually dodges the Boss and walks out the other side, collecting the treasure.
Now, if you're writing about an intentionally bad system, I'd expect to hear about people gaming it, like civilians getting Evasion builds, or sculptors having just Attack, so they can cut through stone like butter.
But no, everybody plays it extremely straight except for the MC and his companion.
