Dunno if theres another thread like this, if so my bad.
My Thoughts (horde): I was introduced to this game about a year ago by a friend. While lvling I came across a few alliance players but never engaged combat and neither did they. My friend on the other hand (a trashtalker and such, you know the type) killed all alliance on sight reguardless of their lvl saying that we should kill them because thats what we hordies do. I didn't take his advice but when I hit BC and WOTLK i noticed i was getting ganked quite frequently by alliance and it started to annoy me. Once i was lvling my second toon to 80 I would usually keep my main close by in flying range in case i got ganked and would go by the moto "I wont attack you but if you attack me im gona kill you" (By the way i suck at PVP so in a 1 on 1 gank I usually always lose).
This worked well till 1 day i was happily strolling in hellfire on my DK when i was ganked by 2 80's who then proceeded to camp me for a good hour. I got on my main but they killed that too, with ease.
After that I pretty much cracked and started killing alliance on sight reguardless of lvl, and since then It has been like that.
The other day I was flying in hellfire questing for C.E. rep when i saw 3 lvl 60-65s alliance doing a group quest. I dismounted and 1 shotted 2 of them and the other mounted and flew away on his 150%. I then proceeded to track him down on my 310% and kill him. Once I killed him I felt pretty bad. And I realised i was pretty much no better than those dickheads who ganked me back in hellfire on my DK. I realise that there will always be dickheads on either faction but I dont plan on being one. I know "This is World PVP" but im pretty sure it's designed to allow fun pvp between similar lvls.
From now on every time I get ganked on my alts by an 80, im going to put a strike on my notepad, and the next low lvl alliance I see on my 80 im gona kill. I know that technically thats not really fair but meh, Its fair enough and it will make me feel much better.
