I read through the guide, and I must say it is pretty solid.
You could write something about energy management, even though it's not nearly as important as it used to be.
Regarding comps, HC RLS (RLS with a spriest instead of lock) is very viable, I've run it up to 2,3k.
I also feel that no guide is complete without some history. Another thing I love is pvp movies. Here's some movies you definately need to include!
Grim - Total Annihilation
Grim - Total Annihilation By Grim - World of Warcraft Movies
Mute - World of Roguecraft 1
The World of Roguecraft - Episode 1 By Mute - World of Warcraft Movies
Akrios - Eviscerate Arenas vol. VI
Eviscerate Arenas Vol. VI By Akrios - World of Warcraft Movies
Reckful - Reckful My Bro 3kBG9 Sdance
RECKFUL MY BRO- 3kBG9 Sdance By Neilyo - World of Warcraft Movies
