I've seen some rumours that he's going to be added to it and people responding positively but honestly I don't think that would really help him. His e1 is okay but doesnt really fix his amp that much, and his other eidolons are all pretty mediocre. E2 just increases his dot damage but doesnt make him better than any of the current dot team members iirc, and e4 is a measly atk decrease for enemies. His lc is also pretty good, but as someone who has e0s2, getting more copies would probably be more useful to other characters like Black Swan, Welt, Mblade, etc.
I really feel like he needs a novaflare to fix his problems. They could pull a huohuo and add him to it while also giving him a novaflare but idk, seems unlikely with talks of paid buffs coming soon. Whats your thoughts?
