to be fair sometimes you have to zoom into first person mode and walk right into the person to interact (when tons of people around), if you go afk for a min or two to get a drink you may forget to back off and thus contribute to the problem.

I think in wotlk the battlemasters have been replaced by portal thingies, still don't understand why they don't just put them up on pedestals and even better like WAR let you queue anywhere in the world.
