The level tracking is done per character. The restriction on who can be granted to, i.e. the referrer is done on account.

Example:

Account A refers Account B. Account C is not connected.

Characters Alice and Bob are leveled from 1-60 on Account A and B. Account C has a level 30, Chris.


Bob has 29 levels to grant. They can be granted to any character level 59 or lower on Account A.
Alice has 29 levels to grant. She can not grant them to any character, as Account A is not referred by any account.
Chris has no levels to grant.

If you transferred Chris to account A, Bob could grant him all 29 levels.

You used to be able to transfer Alice to account B, in which case you could then grant 29 levels to a character on account A. I have not tested this since my last RaF, so I can't confirm if this still works.

One other thing worth noting; levels recieved from RaF granting will earn you levels. If you were to create account D, refered by Account B and a character on D granted 10 levels to a character on B, then that character on B could grant 5 levels to account A. This still works and I have confirmed it last week.

As for what characters to grant levels to, I suggest you give them to the characters you are least likely to have fun leveling or are hardest to box. I tend to grant to melee classes. This way I can get them to 60 and play them where they start to be fun. I don't mind leveling hunters or mages since I can box them easily and still enjoy them at lower levels. I can't see myself boxing a group of 3 pallies, a rogue and a warrior though.
