tanks, str vs vit in HS?

[DWolfwood]

No encounter currently in game requires a high enough amount of hp to warrant the use of VIT accessories.

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.
