How about this for vaulting?

Okay so what about changing the vault to be like this?

First we would have to change the order of boosted 4*. Since there are 5 boosted in a week have one of those be a new 4* and the other 4 be old 4* (also this might be currently implemented I'm not sure)

From there have the vaults be the 12 newest plus the 4 that are boosted.

This would allow people to hoard and try to go for their favorites, have the new 12 be more prevalent, and have it be predictable for when you want to draw.

Like for now it would be the 12 + red hulk, x23, miles, and cho.

Would this be a compromise that the community would be interested in?
