Thank you all again, I ran the first dungeon (Sastasha Seagrot) last night and it went very smooth. I over leveled it a bit and had to sync down.

Opening with 2x Overpower and 1x Flash, and cycling through my cool downs as needed made the dungeon a breeze. I think the healer was DPSing more than healing for most of the run.

Wanting to maximize as much as I can, does anyone have any suggestions on what cross class skills I could get that would increase my tanking (or damage while tanking) performance while leveling?

For example I was thinking about getting Second Wind from the PUG or Invigorate from LNC ...
