The Vault was praised because you would pull a reward out, and you wouldn’t pull it again thus upping your % to obtain the specific item you are trying for. However with only 10 tokens and 300 rewards, your chances seem pretty slim to obtain that desired cover. Note that it was confirmed that tacos will be split between Sweet and Savory, so saving 100 tokens means you will have to save 200.
I decided to do some number crunching to see what kind of gains you can get by saving. This graph depicts it pretty well as it shows the % gain for waiting every 10 intervals. Math isn’t my forte, but I think I am competent enough to not have fouled up the numbers. ![]()

You start getting a benefit from the Vault system at around 100 tokens, at which point your benefit grows rapidly, leaving little reason not to wait another 10 tokens, then another.
This leaves players 2 options:
A. Use tokens immediately and forget about waiting. This makes it a better version of what we used to have.
B. Save 600 tokens (300 for both taco types), and pull until you get what you want then continue to save.
So if you want to use the system, you will be waiting (600/365*2) .821 years, so about 10 months.
