Why are the Tauren the nicest players?

The Tauren are absolute bros. If you shout for help, you're lost, or you're stuck it's always a big bruising Tauren Shaman that comes to get you. In a guild, if you get into any bother it's them that's right between you and whatever it is and they're chill as anything. I've been on the Alliance bumping into them, they're the ones who just wave at you and don't give you any bother what so ever and carry on. It's like people who are chill and very outdoorsy go them.
