is he the worst est in the history of est's? the only notable thing is him having base A rank staffs, but by late chapter 9 early chapter 10 you should have atleast a staff user close to promo which gives them A rank. his replacement is also possibly better than him because he gets paragon and a berserk staff. I still wouldn't take the time out of my day to train him, but paragon lessens the pain of leveling a stafflocked unit atleast a little bit.
