The problem with having one fast Hime is that... well, that doesn't really do anything for you. Vohu will be ready to burst on turn 3 yes, but then what? Your third slot is still at ~20 burst, and ~6 turns away from being ready.
Bring Saraswati to back her up and then you'll have a fast Water team. Either one alone... doesn't do all that much. But Saraswati by herself is... more than than lacking if you ask me.
