Even though Sol couldn't show her true powers at Ixion, she DID still gimp Ixion's attack. Which is what makes Sol so goddamn OP, the -20% C frame debuff. This will get slightly nerfed in Valentine patch, but Sol will still help. A lot.Uuuh? Why would you waste the EX-skill on something when you can just bring Cass instead? The loss of 400 Heal is far, far less than losing your EX slot.
