I have a Cuirass Armor 4 slots, fully grinded. I have also found a Arquebus Armor # Slots and a Dragon Wing 4 Slots. Do not know which to use. Should I keep my current armor or swich, Which can be better tweaked with upgraded. I have a few master powers, and the whole assortment of hero units.

Advice anyone, what do you use. I am only in HM right now.
