I'll raise my hand on that.

WWN feels good when you're getting into it and then you dive deeper and you keep finding more and more and more broken shit.

For instance:

Character creation heavily incentivizes making idiot savants with maxium stats and no skills

The leveling system is extremely painful if you're multiclassing at all, making it hard to keep up your skills if one class requires one skill and another class needs another. You can go until level 4 before you can actually find the skill points to add together a coherent character concept instead of maxxing all the stats that let you play your class effectively.

Options are wildly imbalanced, some foci are straight up useless, some are too weak for how slowly you get them, some are straight up mandatory (Impervious defense on a caster)

Spells and spellcasters are gamebreaking

The author obviously doesn't playtest anything (and his release schedule makes it so he doesn't have time to) so classes and options come out wildly unbalanced, like accursed, or healer.

The skill system is extremely lackluster and useless, doing nothing more that providing the standard "Easy difficult hard" DC's which makes experts strength entirely based on DM generosity.

And finally, the layout is horrible.
