Actually, she isn't.

She's done more than you think: in addition to taking out a bunch of Soldat, she's healed Shinji, Omaeda, Omaeda's sister, and Sui-Feng. So in this particular battle she isn't useless; not just because she's a decent healer, but she's also proficient in Kido as well, which will definitely come in handy.
