sure bro :)
why i dont see option vault to be free tho? :o
Because I was going to use this for another Suggestion... difference;
Guild Points are used for Guild Member Vault (outside of personal vault).
How is it used? That would be up to the Guild Members, it would also be good for Transfer skill items between members without a fee (100 fg for 7 days).
Pretty sure this would be better as a different suggestion, just haven't got around to it.

Vault should have like 25 free slots then pay for more. The advantage of having a vault is huge and feels like a pay-to-win feature. You cant even play in a group without a vault.
Would be nice to get something for free ... my suggestion is somewhat of a compromise.
Also, I did not add in the fact that if a person has like 2 or 15 items in the vault and it has expired, they can pay that amount of fg: 2 (if 2 items) or 15 (if 15 items) are in vault for 30 days.
