So the basic idea is that a level capped character will be able to form some sort of relationship with a newbie (under lvl 10) and will help them progress through the game.
They would answer questions, and help them out with leveling.

When the student is 'raised', the Mentor would get some kind of reward. Perhaps have in the avatar screen "Player12345 Has raised: 4 Students."
After 10 students are raised, the Mentor could be given a cape or something, of different colours for 10, 20 and 30 students, etc.


Either person could leave the relationship at any time. Making it vital that the Mentor actually provides some help to the student, and also that the student is reasonable.

Only one student/Mentor at a time per character.

Once a student has been raised, the student and mentor should be linked together forever, perhaps with some kind of buff when they are together, or a unique ability.

If this suggestion was implemented it would result in lots of high level characters hanging in town, actually asking newbies if they wanted help.
