What this could mean for WAR and DRK?
WAR:
The typical raid WAR (especially in Alexander Savage) would usually be the OT to dish out dps almost equivilant to a DRG or MNK with they slaying gear they love so much. With the new changes in VIT, this could not only balance WAR strength, but also encourage our OT heros to switch to a main tank perspective.
DRK:
DRKs in my opinion excel more as a MT than OT in my opinion due to their mana management. However, they can still do amazing dps with full slaying gear. This change in VIT coming to DRKs may neither be too overpowered nor too gimped, as DRK was first meant to be the go-between of the 3 tank classes. Speculation for me is unknown.
