Nandi does not give a big attack boost at only 30%, but gives some 20% extra burst filling rate, so I thought she could be decent as a main Eidolon in a Light burst build I considered - just needs to have lots of friends with Yule Goat, which I have: with Zeal boosted by Nandi, how fast could I Full Burst things?

Giving Berserk as her summon effect, though, beats the purpose of building up burst meter, as one kami wouldn't burst while in Berserk... but then again maybe that hypothetical build would Full Burst so often I will never need more than 10 turns to finish enemies off, and I could avoid using her Summon Attack altogether. Thoughts?
