Where to start...
Lets start here: I don't mind getting ganked. I really really don't. I do mind getting ganked 3 times straight by the same person right after corpse runs but who doesn't? But I want to clarify that if your dear level 70 comes along and see's me. I EXPECT to die, I'm on a PVP server.
If there was a /whimper, though I could go ghostwolf form, /dance /sleep /whimper and you'd feel bad and pat me or /chicken me and you would wander away. Sort of like a feign death in PVP. And if not... well like I said I was expecting to die. To me this is just another weapon.
Why not /wave or /kiss? Because too many times I see people use those emotes as combat openers. And I don't want any suggestion of a threat. I'm a wolf showing my belly to a bigger wolf hoping he'll just go away.
As for PVP with people who are not 10+ levels higher than me. Like multiple people have commented.... 90% of the time the winner is the person who sees the other person first. I know that if you are busy xping and I hit you while you are busy... my odds skyrocket. I can easily kill a warrior 4 levels higher than me if he's also fighting a leapard his level at the same time. Or if a mage is sitting regenning his mana, I know I can kill him in 2 shocks and 2 axe swings no crits and he can't really stop me. So why would I let him stand up gear up and get ready to go?
I know I won't camp his body... infact most of the time I immediantly leave the area to avoid escalation or the roaming packs of level 70 hunters that invaribly show up when people get into a ganking war.
Now for PVP with people 10+ levels lower than me. I don't hunt in newbie zones, I don't raid low level alliance towns. But if you show up on a road that I'm walking on, and I can oneshot you with a shock? Yer dead. Now if I can't one shot you... I probably won't bother trying to kill you in the 3 blows it will take. But otherwise you are free game.
The only exception to this? Fisherorcs. I won't kill/attack/look-at-funny someone who is fishing. That fishing pole? Thats the white flag of awesomeness.
Does this mean I gank every one I see? No. I only attack if I'm in the mood. Otherwise I avoid and keep a watchful eye out. Several times I have escorted/assisted alliance if they are in the same area as me and I felt generious. But we are on a PVP server, anyone and everyone is fair game. And as in war, anything is fair if you live to tell about it.
