Like even when I make a small scale RPG, my damage formulas and scaling and so on are my bread and butter. I obsess over them. I would accept being wrong about the resulting experience and having to adjust, but to me it's really unacceptable to have oversights and mistakes there.
So something like how broken resistance was, or different types of scaling implemented wrong. That's not disagreeing about the outcome. That's clear oversight in what I consider the heart of the game.
Or for example how the mount's controls with mouse were just remapped from joystick and you have to put your mouse at the edge of the screen to go fast.
I don't understand how to reconcile such a big and well made game with many baffling oversights in the game's core systems. Feels competent and amateurish at the same time.
