I ran into this a few months ago and per one of the WGT responders (sorry don't recall who answered) to my question a new/recent guidline had been put into place. A player has to be in the" amateur" tier or" above" to be able to even have the option of gifting, along with the other advice given by the recent replys.
You might want to verify this with WGT support just in case it has changed since, approx. 3-4 months ago.
