My priority for stats are MND >> INT >> PIE >> VIT atm. IIRC my mind is about 140, INT is about 110, and PIE is at 90. My vit sits at 40, and i dont have points in anything else. I honestly should remove those 40 points in vit, as well... They're pretty useless to me. I only group... I group grind, I group leve, and I group for NM's so the vit is nothing but wasted points for me, seeing as my shell's tank is pretty amazing. Our casters and archers pretty much never get hit... The only time an archer might take 1 or 2 blows is on a hate reset on Buffalo, but even then its really rare. VIT to my THM is a wasted attribute, and having lower vit seems to boost my shadowsears as well. Not by much, mind you, but when i used to have 90 vit, then dropped to 40 i noticed about a 55-60 damage increase off the average cast against NM's.

Only reason i see a THM ever needing VIT is if they're soloing, or if they group with a terrible tank. The THM cone is so massive that you will never be in any mob's AOE if you use it correctly. Just position yourself better, and recruit a gladiator who can hold hate! You only need 1 tank for every NM... I don't see why people multi-tank adds... It's silly and wasteful.
