It would be nice if she got a few more elemental based spirits, so she's more flexible in her attack types.

Right now the majority of attacks her spirits can do are a variety of physical attacks or support abilities. Only Aquarius' water is clearly non physical with Virgo and Scorpio possibly being earth-magic based and Leo might posses light magic.

I guess Leo might still retain his old ring magic in addition to his spirit powers, but we havn't seem him use it since he returned to the spirit realm.

So pheonix, fornax or draco for a fire-based spirit might come in very handy (especially when fighting together with Natsu).
