In my early days of WoW back in Vanilla - just after the Battleground patches - it was a gank fest as soon as you found yourself in Duskwood and STV, but it taught me to be a better player. I learned to stay off the main roads and to hide behind cover whenever a higher level player was nearby. I could even lay down on the ground and shadow meld to blend into the terrain. Getting to AQ40 or MC/BWL was like running through the gauntlet on most days.
World PvP is pretty much non-existent even on PvP realms, especially on maps where dailies are involved and people don't want to start wars over it.
