One thing I noticed is that sometimes successful FD does not wipe you from agro list, you are still in combat mode regenning 1 HP/tick and it lasts forever. Mobs will not forget you and will not go away. It happened much more often when I FD right under mob feet.

In VG you can have two targets at the same time - offensive (for detrimental spells) and defensive (for beneficial spells). If your current defensive target is a healer, then this ability will increase agro to healer (no good).

On level 13 duoing with my wife (13 shaman), I have no chances against even level 4-dot mobs. We can take max 2 yellow 3 dot mobs.
I do not usually have any problems in holding agro from shaman. As far as ability to take damage - it is pretty close to shaman's. Plate classes such as DK take damage much better.

PM system looks broken - requests to enter code from image and no image is displayed.

I am only lvl 13, but here is lvl 12 ability info:
Crescent Kick II: Dragon Discipline, costs 15 End, range: 5, refresh: 8.0, down-arrow-plus Shaken, down-arrow Staggered.

Your ability page also lists "Thousand Fists I" as a lvl 12 ability, but it was not on Martok and Khal trainers.

I am only lvl 13, but from what I heard it has 8 seconds cooldown timer. Sorry I do not any other info till I ding 14 (maybe tonight).
