Aegis is very powerful, though necessary for PLD tanking. Most PLDs want it to block more. I'm okay if it doesn't. I think SIRD on it would be an awesome compromise.

Ochain isn't OP and the JSE shield outshines it in some scenarios. Yes, absolutely, Ochain used to be OP. Maybe 100% blocking outside of a specialized set (I'd be okay with that) is overpowered, but with priwen available and Ochain much easier to obtain, I don't think buffs would be unreasonable.
