Thats not a misconception, your talking about social aspects and item finding. You've reached the top of skilling, now everything else is just extras.
Eve has social aspects out the ass, and tons of uber rare ships and items. But not only will you never get all the great items, you'll never get to the top of the skill tree as well.
Character levels, classes (Forcing you to start over to do something new) are all tools to create a game that has a life expectancy for the average player of a couple months.
Eve is shooting for the average player playing for years not months.
Eve stands out in the crowd because of this, and because of this most people with short attention spans don't like the idea of never having the feeling of "nice I've gone as far as I can go, no one is higher then me!"
You can't say that teamwork and instances and crap are an actual metric of accomplishment, and I venture actual items/treasure can't be considered an accomplishment either, maybe but not in the same way as levels.
I don't like levels, and I don't like classes, both are pointless and serve only to (a) give immediate gratification to the player by seeing a level gain or knowing hes better then someone else and (

to limit your potential and force you to start over to do something new.
Eve handles things nicely in that there isn't really levels exactly... there is no grinding to advance and there is no limitations to what you can do.
