Here are my stats from the event, for those that care about such things:

Map 1, 25 runs, 5 witches.
Map 4, 21 runs, 3 archers, 1 heavy, 2 plat armors.
Map 5, 24 runs, 4 angels, 2 healers, 1 mage.
Map 7, all drops on first run.
All maps 3-starred.
One SC spent.

I could use more healers and less angels but since I didn't have any before, she's not unwelcomed. I was expecting to log in earlier and spent some SC but couldn't. With those drops and a perfect unit (my first 100%), I consider this event a success. Let's see what the maintenance bring us.
