Just to confirm...

[Perrigrin]

...I can't not gift levels to a character that is higher level than me?

[Gurblash]

afaik that is correct.

[Multibocks]

positively undeniably correct

edit: reasoning is that someone could just level from 1-10 over and over to get his characters through the "hard" levels by gifting them from 45-60

[Marathon]

100 % correct
