This really is a great guide, thank you for writing it.
A couple minor points, but are important...
At later levels you gain a blind effect with your Flash ability, when you spam Flash while the blind effect is on your targets you DO NOT generate any additional threat.
Keep that in mind if part of your rotation is spamming flash.

Grouping Fight or Flight, Convalescence and Rampart into an attack macro will be really helpful since it is generally a good idea to keep these up as often as possible.

When the healer is occupied with a Raise, or is in the process of healing someone else and you see big damage coming, sentinel is your friend.

Just a couple tips I picked up from tanks better than me.
