OP, luckily for me, my server is small and even though it's a pvp server people generally will not fight each other, even to the point in daily areas they will help each other kill quest bosses...if they hit each other with aoe they shake it off, get out of combat and then leave. So I feel for ya, must suck to accidently hit someone and have them attack you for it. :P
What I hate:
-When you go to take some kind of quest vehicle and it tells you to dismount first instead of automatically doing it for you
-People knowingly parking their mount on top of quest givers
I'm glad I'm not the only one who noticed that. :P
