1. I understand your reasoning and wouldn't mind this. In games it's often hard to tell when geometry or items are blocking you and when they're not.

2. I didn't understand this part very well. I remember the movement-cursor already showing the amount of actions points taken to move (and if they don't, it'll be in the game). I don't think there's need for any special normal attack -treatment in this.

3. If facing affects things in the game, then definitely this is needed.

4. Defence would be nice.

5. Do you mean that currently player 1 can force both players out of combat and flee? I agree, players should be able to decide for themselves if they want to flee or not.
