Red Mage as possible new tank class

[Gardes]

xxx cooldown buff skill
Converts xx% of the Dark Knight's vitality for xx% dmg boost for xx seconds

Essentially cuts down the dark knight's maximum hp regardless of current standing hp for xx seconds for damage boost similar to BfB and when the buff dissipates, the maximum HP will return but his current HP will not change.

Is it solved yet? Should be fun to use and pair with BfB during tumults.
