Vault feedback and suggestions

Hi, I think the vault is generally a good idea that could benefit from some tweaks. For future vaults could we keep the "big vault" and "small vault" but add a "medium vault"? Maybe keep the "medium vault" to 100 items. Some other suggestions:

1) There are probably a bunch of folks transitioning to 2 stars but could we tweak the percentage of 2 stars to 50% or less? I think that would be more than fair.

2) Can we increase the number of 4 stars so that there is at least one of each cover?

3) For the featured 3 stars can we have 2 of each of the 3 colors?

4) For the big vault please keep the iso, health packs, and hero points.

5) For "special" vaults could we also have a sale thrown in as well? icon_e_biggrin.gif Please pretty please with sugar on top?

6) The 50HP daily special is also a good idea. Please keep that.

Thanks!
