"Build Your Own" Vault

FaustianDeal

what if you could have the option of populating your own vault at the risk of having lower drop rates of "really great" stuff?

For example my simulator vault has what I would call
4x 4* prizes (3 covers and a legendary)
28x 3* prizes (all covers)
48x 2* prizes (again all covers)

If you could change the outcomes would you tolerate changing the odds?
3x 4* prizes, but you get to pick them - restricting you to 2 covers of the same color/character
20x 3* prizes, but you got to control what they are - allowing you to pick up to 3 copies of same cover, up to 5 total for the same character?

Right now the essentials are required to be included - this could be preserved, or not. (I would prefer for it not to be.)

And then, probably when you first open the vault, you were given an option... a 'random' vault with the higher drop rates that included things you didn't need, or a vault you were allowed to construct? Would you accept the lower drop rates?

(My best case scenario is that the 'custom' vault be allowed to keep the old ratios, and a 'random' vault be adjusted to have slightly higher ratios of higher value prizes.)
