I think Ezio is OP. I have him at 7 stars and fully enchanted orange. If I'm up against him without a magic user, the enemy single Ezio can take down my entire 5 man physical team, including my own Ezio. That's messed up. He zips around without being targeted, continuing the gain 50 energy every dodge, which is every attack.
Ethera only gains 15 energy per dodge.
I think either Ezio's energy gain needs nerfed, or the amount of time he is untargetable needs to be changed.
I'm happy I have him, and was happy to spend for him. He's great. But honestly, he's breaking the game.
