Is there a Point doing this:
[Chat Chit] DMM FKG-golden-week-gold-gacha.png

I mean is there an actual Chance getting Rainbow Units out of it?
11 Million Gold got me one Rainbow Pot with a High Attack Ampule and one Gold Unit.

If there are no actual Rainbow Units in it then it's kind of a waste of money and i should rather farm the Gold Stage now and ignoring this Gacha, right?
