If you think Horde in Vanilla sat around in Wetlands waiting inside the Inn at Menethil to gank random alliance that just happened to Hearthstone there or go to check quests, you're out of your f*cking mind.
I played Vanilla too, on two of the most populated servers at the time (Kazzak, Ravencrest) - The ganking was never done so methodically to shut down the opposing faction. If I saw a horde when I went through Wetlands it would be a guild story. Now I cannot take any of the boats to go to the other continent without Horde destroying me.
I just checked fyi. Seven horde level 60's standing in Wetlands at the harbor. Seven. Tell me how many alliance are standing like that in Thousand Needles.
