I have to admit, WASD controls wood be nice so I can move my character and search with mouse at the same time.
It would also fix the issue where I accidentally click on a party member instead of moving. Drives me crazy.
Also, I'd like to camera to not be so stuck that I can't look up. Some terrain makes it hard to see ahead of me when moving in Drive mode directly behind the character. I've run into a few traps just because I couldn't see.
