@Naoki Yoshida-> Make Samurai a Tank class!

[ReplicaX]

I agree to a point. However, still can't see it as a counter tank as far as appeal. Seems like a waste for SAM as a job imo.

This why I feel Red Mage is needed and more appealing as a Tank.
A magical Tank stands out compared to the current jobs in the role.

There are many possible directions they can take with it. Offense/Defense Magics (Hybrid of the current stance dancing), Debuffing.

Instead of just a traditional sword or rapier. They could use a "catalyst/device" to produce an aetheric weapon, which can have different enchantments depending on the situation.
