So, prior to today, I only needed 3 frags of Kushina to reach 4 stars, and that is picking her up at an extremely casual rate. So today I figured, may as well 4* her now. so I spent coupons to pick up 24 of the Mission Mobilization Boxes. Went to 4* her, spent 50 Vials...and....nothing. I did get her Mystery maxed out first, but I didn't bother keeping it and I'm glad I did it that way. because I had then spent 20 vials worth of coupons and skill trialed her again and this is the result

So, I started noticing a trend (seen by events like Sakura's Gift and Fireworks event), that if you actually spend coupons on the items that give you random values, you seem to have a higher chance of getting more value out of what you spent with coupons compared to getting them for free. Then add the 20 vials worth I spent on the coupons, I'd like to believe this is true. (I know mods are going to say something like "Oh its just random"), while may be true, there is not enough data to suggest otherwise.

Either way, I'm pretty satisfied with the breaks. I'm not too worried about the standard or the mystery breaks, as I got the more important ones. And so the team I'm currently running (until I find a better idea) is
