I think she would have been good at 6pp even if they had to nerf her stats.

It makes it way more likely that you can swing twice with the bird. She can probably clear wards too to make sure it can hit face. Also, if they kill Maeve, she spawns another statue that ticks down during your Jeanne turn.
