Have you ever made an alt in an online game? (Christ, do I have to define “alt” for you now?) Y’know, an additional character just for screwing around when you tire of your main character? Maybe you’ll take this secondary character all the way to max level, maybe you won’t. That’s the beauty of the alt: it’s usually twinked up the ying-yang and it’s just for sport. No pressure.
Some players are freaking addicted to alts. They never max-level anything, just screw around with one of their 8 or 10 characters until even they, themselves, realize they’re an embarassment to the guild. I’m guessing they just never find their niche or a class they enjoy and can’t complete the deed. Given a long enough timeline, they’d be max level in every class. Which will be good for someday.
By all accounts, these type of players are just now reaching max level in EverQuest-Classic. Dudes, what fun was to be had in EQ has already been had. Let it go.
