There is actually space available for OFFTANKS.

Sometimes, you want a role that does more damage than a tank, but doesn't need to tank all the time.
For example: Garuda ex, Twintania

How it works:
-Does higher damage than a tank on DPS spec, but lower than a DPS class
-As tough as a dragoon in terms of hp and defense
-A skill similar to Aetherflow. This allows them to use a skill to reduce damage for the next hit (removes a stack), OR as long as this Aetherflow buff is up then they take reduced damage but they lose a stack when they are damaged.
-A skill that redirects damage to them (like cover) or changes the target to themselves temporarily (like 1.0 taunt), which has a low CD.

Example usage:
-Tank Garuda sisters (DPS can currently do this)
-Tank twintania's egg hatch
-Take a table flip from Titan, incinerate from Ifrit or Death Sentence from Twintania while main tank is the target (Needs to be timed)


This class would be unable to main tank anything a dragoon can't already i.e. anything serious, because auto attacks from bosses or adds would quickly remove their Aetherflow like buff which they cannot maintain constantly.


tldr an offtank kind of like ffxi ninja except their shadows are severely gimped but have no cast time.
