Wholeheartedly agree. I was reluctant to download mods, but I've finally caved in and tried out the WASD movement + Native Camera Tweaks mods combo and they're really fun, even with the issues they sometimes have.
With how gorgeous this game looks, not having a comfortable third person + WASD movement feels like a waste. Using controller for movement and mouse+keyboard for everything else is an option, I guess, but constantly reloading UI and getting used to two UI layouts is bothersome.
