I think it really more depends on where the player put their bonus attribute points. The difference in gear really isn't that much. I think I mentioned it before but the difference between my full STR and full VIT is about 2200 HP, not enough to really make a difference some of the hits are more than that from a boss fight. In full STR my HP is 14231 total, now when I run dungeons I usually switch it to my mix of 3 STR 2 VIT. I have though forgotten to switch it from full STR, many times. Never once did a healer complain it was too hard keeping me up, or did my health drop so low I would need to hit HG. The DPS difference isn't all that much either. Now I'm just in reference to the 4 man dungeons and 8 man primals. It really doesn't make much difference, if it actually saves time its hardly noticeable.
