I just think you were putting the cart before the horse, so to speak. If the swapped vit/str then the full str war is losing on damage and hp, assuming str would not have the same value as it currently does. I think that if attack power scaled off vitality, str wouldn't matter, it would be a dead stat like dex. Or have a minimal effect like determination.
That's what I was implying exactly. That some people are hoping VIT becomes both the attribute that determines HP and ALSO becomes the primary attack power stat.

So similar to how STR affects MNK/DRG power and DEX affects NIN/BRD/MCH attack power, STR would be dropped from WAR/DRK/PLD damage calculations and become a dead stat, making VIT the ONLY primary stat a Tank needs to worry about. Not counting VIT, Healers and DPS only worry about EITHER STR/MND/INT and no other stat really. In a way it makes sense, since no other stat matters for healers or DPS besides MND/STR respectively (not counting VIT for obvious reasons), whereas tanks had to balance 2 stats. SE *could* make VIT both damage and HP based for tanks, but what I and others are saying is, it would make WARs as strong as they are in full STR CURRENTLY, but now with the addition of 6-7k+ extra HP.
