Why is DRK so squishy and how do I stop it?

OK, your healers being in cleric stance is probably a really big part of it, like, 70 percent of it, and they should really only be using it when burning stuff. But, what are your Cross class skills, because you should at least have foresight because DRK's mitigation skills are mostly focused on magic instead of physical damage?

Right now at level 38 I chose: MRD: Foresight PAL: ummm....taunt? Provoke! Provoke. PAL: Convalescence

I forget the names of the abilities sometimes, I just know what they do. So I have: -20% Damage Incoming (Looks like purple honeycomb, or protect), +20% Parry only useable in Dark Side (Dark Dance I think it is?) then I have +20% Raised Defenses (Foresight), +Healing Received from healing magic (Convalescence) and I think that's it. I may have Bloodbath too.

Thinking about crafting some gear...my gear is: HQ Steel Zweihander, Calvary Helmet, Calvary Chest, Calvary Gloves, Calvary Belt, HQ Toadskin Breeches, Calvary Boots then all HQ Sphene accessories (+3 VIT, +3 PARRY)
