My Lights are my main team right now, and I just unlocked Shingen after the Tower Nero event. I remember a long time ago (I don't post here often) that she was recommended for me and I'm wondering if a) that's still the case, and b) what my battle flow should be like.
My team right now is:

Mordred (thought about Herc but I really like Black Propaganda + Sniper Shot, and now I have Shingen to try)
Tsukuyomi 80
Michael Awakened 80
Sol Awakened 80
Eros 80
---------
Frey 70
Atum 70

If Shingen is the way to go, I assume I should work on getting her lance weapon? And what's the best way to use her? With Mordred I've just been dropping the debuffs and going ham on attacks, saving my bursts until the enemy goes into rage and buffing up with Michael before I launch it. But Shingen looks quite a bit different, so I'm wondering precisely when to use her skills and how often I should actually be bursting. I'm a bit scared of dropping BP and SS, so I need some convincing.

And while I'm at it, I feel a bit iffy about Frey and Atum in the back. I also have Santa Satan as the last of my light SSRs, but I don't think she's that great. Are there any SRs or even Rs I should consider running instead?
