Levi's comeback with full power or let him remain according to the manga line?
Remain like the slug he is.
I feel like Levi being weakened and unable to fight makes the story more interesting, because we can't just deal with every problem by throwing Levi at it.
He’s not cool as a cripple.
I think stick to the original story line and anyway, we have our Queen Mikasa who’s just as good as Levi.
Levi! Come back with full power!
What do you think?
