Not long ago, Cadet Elisa used to have her job skill as cure (the ones which Anis and Valeria currently use). This was later removed since Mass Healing was reworked and both the Elisa's got it as their skills. Cadet Elisa was better off with cure, mainly because of how buggy it can be. The skill apparently heals faction members who aren't in your squad so it doesn't benefit them. Giving Cadet Elisa cure again would be much more convenient
