I'm not sure people are understanding the OP's point, SE have a one request per ACCOUNT restriction, not one request per CHARACTER. In the case of FFXI a 'request' is a single 'character', while in FFXIV as I just discovered a 'request' is up to two characters.

So, those arguing about multiple restorations per character simply don't understand the reality, and I don't think the OP is talking about that issue.
