This is my first event comming up.
I have 2 questions.

1) Is the primary goal during the event to grind as many Odette Units as possible, or are a couple enough, and it's better to do missions giving more DC?

2) Any info on how good that 2 Spotlight uints are? I may get 5 SC during this week, should I use them now (got Monica but none of the others), or are those units better, and save the SC for the event?
