Go full Vit for stat allocation and have a VIT jewlery set as well as a DPS one (or even better a gryphonskin set).
Depending on content I'm doing, I'll either go full VIT accessories or full DPS or a mix of both.
The idea is to reach an HP pool you'll be comfortable tanking and use the rest to increase damage.

I have a full set of gryhponskin accesories penda melded with VIT, Parry and Crit and it's really wonderfull. I'll be sitting at 8300HP in party (vs 8800HP in full vit) but my DPS increased by 40% and the extra mitigation from slightly high parry reduction and rate.
