LOL ... when I see an person from the other faction, I use my spread out macro so that they know exactly how many of us there are... then they back up.

I do a /dance, mount up, circle around him with all my toons with all my elephants... then I continue questing.

Most of the time, they follow me to see how fast I kill stuff, so I start killing stuff, /wave then move on.

Of course, every level I get closer to 70, this becomes much more easier when dealing with others.
