I demand one for all so i can figure out what happens with yuumi

i doubt it being that iirc shes untargetable while bound.

if they do bring it back tho, we can finally answer one of sciences greatest mysteries: if neeko turns into neeko, what does she look like?

Imagine 1 Yuumi building full tank and the other 4 just binding on to her, all building full AP. If possible, the tank Yuumi might actually end up with a decent amount of AP because of all the other Yuumis. It might seem kind of bad because even a Yuumi building full tank probably can't tank a whole enemy team for that long, but you have to remember the insane amount of heals and shields she's be getting as well. My guess, though, is that you probably couldn't have more than one Yuumi on another. Who knows, though.
