They're just totally outclassed by EVERYTHING. Maybe double their effectiveness, then they'll actually have a place instead of just being eyecandy and completely impractical in combat. Stuff like Gladiator Armor, Odysseus Armor, and the Armor of Typhon. Kinda sucks since they look incredibly wicked.
NOTE the default (gladiator) weapons (and reskins) are fine. In fact they can be pretty OP in the right hands because of their combo chaining.
