Actually, if you gift levels to a character, they can gift levels to another character. But the inital Veteran/Friend rules apply. So, like say I have a 4 man team. One is the Veteran, one is linked to it. And the last two are linked to the previous. You level all 4 to 60, now you have 4 60s. Characters on account C and D grant a character on account B levels to 60. Now Account B has 2 Characters at 60, you grant a character on the veteran account levels up to 30 from one character on Account B, then another 30 with the other 60. So, you end up with 6 60s in this case.
