Well, lackluster in comparison to the rest of the light pool is a given, but that's kinda an unfair comparison considering that rest of the light pool is unbelievably borken...
... in comparison to elements like dark which get utterly shafted in so many aspects. Seriously. Can Pluto not be the only one to be a team player in a dark setup, and can dark get something to buff their BG cycle as a whole?
Edit:
LSatan's buffs: GDA becomes GDATA, nuke comes down to 5t cd, skill 2 becomes 6t cd and gains additional crit buff. Burst effect: additional pursuit dmg on normal atks for 3t.
... which isn't phenomenal to say, but at least it isn't utter garbage.
