And then I discovered the wonders of the awesome Vampire Beam.
Now he's in my frontline as one of the boss softeners.
Just a question, who else has those useful post movement status inflicting attacks like SRX' TenjouTengha Nendou Ken (armor down) and RV's energy siphon Vampire Beam? I hardly paid attention to these things until I noticed recently how useful they are...at Scenario 50! -_-
You could always put him in something that's not the RV. He's a valid choice for a Type-3 subpilot due to his SP Regen and Accel. Or you could have him fight in something else. I feel like it's not that he's getting weaker, but everyone else is getting stronger. I hope he gets powered-up somehow in 3rd OGs or 2nd OGs Gaiden (if such things will exist).
Fun Fact: his VA is going on to voice Han Dang in Dynasty Warriors 8. If the game doesn't get dubbed, you'll be hearing him an awful lot.
