Mount riding - control problem
I will agree that WASD movement on the raptor (at least) is a bit strange. However, I found that mouse movement (W/S + Right mouse button) to be very intuitive and control nicely.
It’s not a problem, just different controls. If controls were same as on foot then we would have jerky movements and unrealistic turning around. And that would be pretty much just slapping a skin on superspeed.
