I've been searching the entire internet for a thread dedicated to this issue, and I just can't understand why no one is discussing it. Is there no way to map the camera to WASD instead of the arrows? What weird hand position did the creators picture? Finally I tried using BetterTouchTool but that wasn't compatible with the game, so the commands didn't apply for some reason. Does anyone have a solution for this?

I think your only chance is to create a custom keyboard layout that switches the wasd keys with the arrow keys.

You might need a third party mapping program to do that. The game's very click heavy so the developers probably assumed most people would move the camera with the mouse.
