The thing is, you would either need to make those high-tier rewards accessible to everyone in which case they lose a lot of their shine. Or you need to design it so that only a very small % of players will be able to achieve them.
There are those who are willing to play an MMO for 16 hours a day, so if you make them rare enough these are the only people who will be able to achieve them.
I remember Star wars galaxies, I didn't play it much myself
but I remember "play as a Jedi" being a big selling point and apparently this was in reality only possible if you were literally willing to devote your life to the game.
They changed it some years later so just about everyone could become a Jedi and there was much uproar from what I remember.
