You know the "defensive" line gear? Only 5* gets specialized defense, but the rest of the alchemy line and Ancient Plate have pure normal defense, which is non existent in T2 and T3. Normal damage is there, but the armor doesn't provide enough to negate anything really. Ironmight has stun resist, but no pierce dealing enemies deal stun; the set really has no place anywhere. On the other hand, Volcanic Plate has stun AND fire; 2 natural status resistance, both of which are common by the elemental damage dealing enemies and makes it quite at home in FSC. Ancient Plate set is neato that it has the highest defense and natural bonus health... but still it doesn't protect you from much in T3. Maybe T1, but not T3.

So my question is, what situation would prompt you to use any of the plate gear at all?

Is it really a crown sink waste of space?
