Dark Knight - Cross Class Skills

[ZodiacSoldier]

Was wondering what is everyone taking for Dark Knight Cross Class skills?

Required
Provoke - No Brainer

Good Options
Convalescence - Increased Heals is good.
Foresight - Another Defensive CD.
Bloodbath - Self Healing is good
Awareness - Stops you from getting crit, not the best but decent.
Mercy Stroke - OCD Damage and possible heal (unreliable though), but cooldown is a little long.
This have saved me a bunch of time though with the heal either when i'm soloing or in a dungeon if the healer dies to mechanics/aoe and i can eat an add.

Maybe
Flash - Not sure about this one since DRK actually need their MP for stuff unlike WAR who can use it after Berserk. Untraited version don't even blind. DRK also have unleashed which cost a little more but also does damage.
Fracture - Not sure if it is worth it for the untraited version.

Bad Options
Savage Blade - Don't know why a combo skill is a cross class option
Skull Sunder - See above

Instead of these two abilities I wish SE would change the cross class options to maybe these skills:
Berserk - great ability but it's probably too much of a signature ability of WAR since they are kinda like berserkers.
Thrill of Battle - a great CD and Heal

Rampart / Sentinel - Great defensive CD
Fight or Flight - a great DPS CD
