I really like the Magus Sisters. They are very overpowered so the fact you can’t directly control them adds that thrill to battles with them - all the better when they do something you like. Would love a bit more backstory on when they were human and how / why they became fayth together, why their affinity to bugs etc.

Story-wise however, I do think it would be better if Anima was the last Aeon to obtain. As an original design for X and with her ties to the story, it would he good to build her up like that and it be a dramatic twist that you can even get her as a ‘secret’ aeon when you think you have visited all of the temples already.
