is there an option in assassin's creed odyssey that let's me move my character like i would move in WoW? like changing direction when holding down W and moving the mouse.
I can't seem to move my camera with my mouse. that's the main issue.
Not likely. Assassin's Creed Odyssey is an action game, not made for tab-targeting move sets. Spend some time learning to aim the camera with your mouse. I recommend an fps or other action games.
