Cure V, Raise II Where?

[Valkrist]

Tanks won't have 1400 hp at 99.

A galka PLD/NIN gained 79 HP from level 82 to level 90. Extrapolating on that, a level 99 galka PLD/NIN will have about 1633 HP without gear or merits.

A galka PLD/NIN gained a grand total of 148 HP from level 75 to 90. Is that 148 HP outside of Abyssea demanding a Cure V to make up the difference?

This still doesn't produce a viable reason for why a RDM or a SCH needs Cure V.
