She specializes in support because that's what her foster mother taught her to the exclusion of everything else.

The first offensive moves that Wendy used, she only learned from copying Natsu (roar and wing attack).

Never having had the option of learning attack magic isn't quite the same thing as intentionally specializing in support spells.

And even specialists should know a few other things, in case their speciality isn't of any use in the situation. What good is support magic going to do her, if her teammates are down, or if she's caught by an enemy on her own?
