Let me first start out by saying I am an alliance player and am a level 58 Pally. (I can see the hate already, haha) Maybe I'm just too into my class, but I generally don't mind Horde players at all. I see the lower levels (no honor) around Hillsbrad all the time. I find more pleasure out of lower levels being surprised that you're not going to gank them. Throw a couple waves up and leave em be. It's just what I do. Only if you attack me, then, it's on.
(Just a side thought): I honestly cannot stand other Pallys bubble hearthing and a lot of fellow pallys say the same thing (even though every class should use their abilities to the fullest even if it seems cheap) If a bunch of 60s roll by and start attacking, if anything, I'll bubble, laydown, or beg, just to put on a show. I laugh, they laugh, it's fun, its the point of any game.
