Eh, I dunno about that. He's a solid Buster AoE Archer with a decent Charisma, an NP damage boost, and an NP charge. His NP charge gives him Ignore Invincible, which, on top of his NP's native DEF ignoring properties, basically means he is doing his full damage to every enemy whenever he erupts. Sure, there are better Archers generally - Squirtoria still dominates the class - and even better Buster AoE Archers - Gilgamesh continues to exist - but he's pretty competent.
Especially if your only 5-star Archer is, say, Orion. Like mine is.
So, yeah, don't sell Everyone's Favorite Fighting Frenchman up short. Pun intended.
