There is so many problems with this suggestion that I think majority denies it. This can be abused, and like someone mentioned, getting a nrg to a person who is level 1, doesnt make sense,and causes unbalance to the server.
It also doesn't make sense, since the point of leveling up is to acheive some of these features as you progress through the game, so it feels like you've earned it the right way.
