What they mean by "change the damage calculations of tanks"?

[Cynric]

Well let's look at what doing each assumption would do.
1) Split damage between vit and str. If they make it so str has a higher impact on damage then nothing would change, we'd still roll with enough vit for the fight and use the rest str. If they make vit have the higher impact than they might as well just make vit = attack power. Because we'd roll with all vit. No reason to take the less impacting stat.

2)Make enmity gain higher the more vit you have. This would still not change anything as once you generate enough enmity in a fight you don't need to generate much more, It might help a vit stacking paladin but we'd probably still push str for dps.

3) Heavily reduce tank DPS, Well considering they said they felt warrior was in a good place I kind of doubt they're going to do a global reduction of DPS on tanks. This would also cause trouble for tanks leveling and make the more DPS oriented tank kits kind of pointless.

The only reasonable thing I see for them to do is make vit = AP, doing a STR/VIT split is pointless, changing enmity doesn't exactly have anything to do with damage calculations specifically either. If they were going to change enmity to scale with vit I think they would have specifically said enmity calculation anyway not damage. Even if that is what they meant there wouldn't be very much point to that either.

Even if they do scale Attack power with vitality we wouldn't double dip into the strength stat on current gear because we wouldn't use it. Stats don't work like that currently. Strength isn't a flat melee damage increase, It's just the stat most of the melee jobs read to get their attack power stat from. Then the game reads that attack power stat for the weapon skills that use it. Ninja is a melee and dexterity increases their attack power which still applies to their physical damaging skills(and self heals that scale with AP)
