Pretty much agree with Micah and Isengrim.
As long as epic char (when it comes to lvl) doesn't "abuse" his epic skills, making the other players grumpy and making them losing fun of playing Avlis (I met such char literally ONCE), I am totally fine with his levels, even if gained them in ridiculously short period of time.
Some players don't like ganing xp. Some care for it more than the others. Some would like to gain xp and don't know how to do it effectively. Some are dirty PGers (and they DO dissapear from Avlis quickly), some are cute PGers, make other people laugh and become RPotM (
*waves at Pinky* 
). Would you like Rhiss less/more if he had 8 lvls less/more? Or rather change the question: who cares??
Never met Janur IG, but char I will forever remember is Lucien. I doubt he passed by lvl 12. And always RPs with him were something special. He ROLEPLAYED powerful and strong personality, even if he was level 12. If player makes you forgetting about his char's level, it proves his value as an excellent RPer. Which is the first step to real epicness, despite number of levels.
Honestly, I can't understand this fear, that some complete n00b will appear on Avlis and powergame to level 35 in 6 months. So what? His levels don't grant him epicness glory in the eyes of players, who are here for years. He just has levels, he doesn't have fame. And each real epic HAS his legend.
And capping... it reminds me communist regime. Yeah, let's make everybody equal, then everybody will be happy. Hey, why not make it 0-15...? We are even more equal! Come on HFox... if you think, your char is anyhow "worse", because he has less levels than some fake epics... then we must work on your self-esteem, really.
*hangs big poster above his bed : I am the hero of Avlis and everybody loves me!*
