The only purpose I can see is for Ruby to essentially be a slave driver for the Grimm army. She can't control the Grimm outside of her castle without the help of one of the Seers (which are most likely custom creations). Since Grimm innately fear the warrior bloodline, Ruby could be useful if she was persuaded to join the side of chaos.

I don't think Ruby is entirely loyal to Ozpin. If Qrow dies, she's out of there. Go look at Time to Say Goodbye where she questions Ozpin's cause entirely. She could switch sides at some point in the future.
