I gladly admit that I'm not backing of from a HO if needed, I try to avoid it because its a bad choice from a tacital standpoint but I have no moral concern about it.
U do whats benefits u most in the specific situation, Ho, pick, ram, vulch, run. It is not a pistol duel between gentlemen, its a bar fight with drunk hillbillies...
I learned pretty fast that tail chasing in a furball gets u killed. Just when u have the perfect shot another con blows u out of the sky. If there are more than one red in the vicinity i rather look for deflection shots, it takes a bit to learn to not get too excited when having a con in sight, sometimes its better to give up an opportunity and evade another con instead of going down along with the guy on your 12.
