Hi, new user here.
Phoenix-D, I noticed the same behavior in the demo. What I eventually decided on is that the best way to rectify this problem is to play chicken with your opponent. Set your ship to RAM, once the enemy is within firing range your weapons will of course light him up. If you're still approaching at full speed at a certain distance, the other ship WILL turn. You just have to be ready to switch back into ATTACK mode or else you'll just careen right into him.
