I think the reason I'm so frustrated over the drop rates on the boxes is because I've used similar gachas before, and those not only had smaller total pools of stuff, it was possible (if you had the right item/could shell out some cash) to pull a handful, and pick out the item you wanted.
Anyway, almost cleared out box 2, I'm getting some momentum on getting grindy on the 40 AP quest (oh god I am so not prepared to level SantAlter for the 50 AP quest) for the mats and stars for the CE. I just have to hope I can keep ditt's Marie available as much as I can, since Tarasque into Crocea Mors into Guillotine Breaker is relatively easy to pull off and puts all of the Servants into really close kill range; or somehow hope one of my other friends somehow gets Jack. (Also, ditt, get the Holy Night CE already! :V)
