Well, Mega has a very high multiplier, and with all his buffs, has definite 50 BC generated from two hits. The fact that he has two hits makes him easy to spark with and then gain maximum damage. Then he heals, boosts ATK, and boosts HC drop rate. His damage is further increased by his spark damage from his ES. How is that bad?

Obviously there are nukers with more damage than him, but Mega takes the role of Healer and BC buffer, so you have an open slot to put whatever other unit type you're missing or any unit you want.
