Like past gachas of this type, it's only worth it if you're new and/or want to whale.

Or you're somehow so unlucky that you only have ~5 unique gacha golds over the course of however long you've been playing.

Otherwise, there's a high chance of getting dupes proportional to how long you've been playing/how varied your roster is.

Well I guess I'll skip then, 12 unique gold and 3 rainbow. And event girls aren't that bad too.
And 120usd is just overkill
