Nice guide. Some feedback:

In the class description for GLD, I might add a comment or two about GLD crossclass class skills, especially something about how every tank will eventually require provoke. When I was on the fence about which tank class to start with, that info sold me. In the end I preferred WAR, but don't regret starting with GLD.

I might also add something in the section about initiating pulls to lead with a ranged ability. And that to many dps players, the initial ranged attack is an unspoken signal of which mob you'd like focused first.
