Elfman and Mirajane's backstory was beautifully illustrated in the Phantom Lord Arc, adding a layer of depth, loss, and acceptance to the already exciting story. It gave depth to both characters and saw them both move past the trauma. To have Lisanna return seemed just unnecessary and quite honestly pandering to a select audience who wanted her back, rendering Elfman and Mirajane's torment and grief almost null with her reappearance. On top of that, she doesn't have much of an identity in the new group beyond her devotion to her siblings and the teased relationship between her and Natsu. Just about every member of Fairy Tail at this point has seen some character development, and Lisanna unfortunately has seen the least. That's why she's last, at least in my opinion
