tanks, str vs vit in HS?

[SirTaint]

This isn't true. Having tanked both Bismark EX and Ravana EX many times, there is reason enough to use VIT accessories. You can swap out for STR depending on healers, but VIT makes things MUCH easier. You generally need STR accessories if you're having to carry poor DPS at this point.

VIT accessories doing two of the easiest primals in the game? I don't think so.

Titan ifrit and Garuda were harder at i90

BIS ex allows the use of Stacked CDs for the adds so you should take very little damage.

Ravana just stands there 50% of the fight.
