As of right now, it seems that the only way to transfer items across the same account is to use a third party (player) to trade twice, of which would reduce the potential of equipment by 2. This is incredibly annoying and punishing for having a crafting dedicated character, or having lucked out on one character with getting a certain recipe. Also, even not dealing with equipment, the lack of this feature is a quite time consuming to just transfer any item in the first place.
I’m not sure what would be the fix if you wanted to keep the “Potential” reduction in place, but even then, I feel like it should only be reduced by one point.
(Also, not sure if this is intended or not, but you can’t post in the Beta Tester forums (the category option is missing)).
