4 vaults is too much, I would start giving vaults to the 3 highest ranks, supreme god and titan: 1,2 and 3
Why should this change the fact that donors should get it? Anyways, non-donors get pv1 for free on most game modes. Support!
No support, 4 pv's for titans is too OP and is extremely pay to win. The most any rank should have is 2, but not every rank should get pv's.
