...So, I'm confused about something.

Why would anyone in their right mind do the "Not Owned" Gacha when the Bonus Gacha awarding rainbow medals is also available?

Option #1: Pay $60 for a random 6* you don't own, 12 random rolls at the crappy .5% / 6% odds for 6* and 5* characters, one guaranteed 5* and one 75% / 25% 5* or 6*, and you get manyus and skillblooms. You also get a gold dressbloom, but no rainbow dressbloom. Crap deal.

Option #2: For the same $60 you can roll 33 random characters at the much better 3% / 7% odds for 6* and 5* characters, and you get rainbow medals to choose your 6* waifu. Enough for 1.5 6* waifus at $60. You can also just pay $20 for a roll or $40 for the guaranteed 6* you want. And you can save the medals for whenever your 6* waifu is released.

Why anyone would ever choose Option #1 is beyond me.
