I think that you should be able to attain a certain level of experience with your PVE characters that you would be able to attain a glow that is found in bosses with in the game. I think that if some one was able to amass five million experience on one character they should be able to get not only a title, but also the same glow that is found in bosses. I would think of this as a type of reward for putting some much time in to a character.
One thing that you could also add to this aspect is maybe also adding “Super Skills” to these individuals that have attained so much experience with one character. Maybe it would only be one skill per profession. Granted I don’t have ideas as to what those skills would look like but, I do think that there needs to be more of a reward to those individuals that put in needed time to amass crazy amounts of experience on one character.

.Its should be a bday present.No noob would play the same character for 2 years without a dedication to the game and i think its a perfect way to reward that dedication to the character by making him a boss of humans. ^_^ damn my warrior would love it!
