I don't HO but it's not for courtesy reasons. I try to get more than one kill per sortie and I really don't see how Ho'ing is conducive to that.
And for all those tards who say it takes two to HO. Shaddup noobs! It only takes one to attempt a HO, two to merge.. learn the difference. That said, I'd say well over 90% of HO's are avoidable.
I'll kill anything that presents itself as a target, short of kill stealing. I'll gang, vulch, pick, rope, bait, taunt, switch, fake, tease..... whatever I can do to defeat my opponent and fly to the next victim.
I'd have vulched that 262 and laughed hystercally about it, along w/ anyone else who saw me do it. Exception: If I encounter a friend who is bingo rtb or crippled, I will often let him go(unless someone else is trying to kill him, then it's mine). Unless it's Todd, then my odds are almost 50-50 of winning 1v1.
The game is primarily about plane to plane combat. If you have a chance to shoot another guy down, it's due to mistake(s) he has made, let him have it.
