It's hard to decide specifics of something like dog fighting when there are so many tactics to deal with, whether balanced, unbalanced but sensible, and just cheesy.
=(
I myself have been tempted towards bending the rules just because it would have been poor role play for me to compromise my in-character actions because of rules that don't make full sense to someone like me who sees the fairness in the unfairness of some tactics.
Specifically if you haven't been shot down, I don't understand the no reengaging rule. If you can escape to a safe distance, reposition yourself, and reengage from a more favorable vector, that's the logical strategy for some battles; especially if you were ambushed. Sure some of these tactics seem unfair or can draw out battles, but that's how fighting is sometimes. Often a battle is won when the opponent simply can't keep up and decides to flee simply from being tired of the fight itself.
Gaining distance, taking a breather and assessing one's options before reengaging is also something I tend to do.
But we must try to obey the rules where we can and mediate between players whenever possible. I don't report half the PKs I've suffered under-level because I mediate with some people who fly at me like a bat out of nowhere and blast me to scrap. If we can work it out ourselves to we are both having fun and no one else suffers any slights, it smooths things along a lot for us and keeps the issue out of the admin's hair. (announcing wishes to reengage and giving players a chance to accept or deny that request for example).
Anyway, that's my thoughts about the engagement rules. I know I'm not in any way authorized to make policy or sway public opinion, just sharing the things that have made many RPGs run well for me and my friends in the past.
