Eventually it will be easily available and then, shortly, outdated. This is not what a worthwhile reward looks like to me and that's why right now I'm off this ride.
Hell, relics will probably be 205 or something, and then what? Wow, these hours of taking the pedal to the metal really pay off.
You're describing every mmo with gear progression. You can just wait until a week before the game goes offline in 20 years and then quickly try to knock everything out with ilevel 2000 gear, but that kind of defeats the purpose as well.
If you enjoy the game you do this stuff so that you can continue to do the harder/newer stuff, if you're content waiting and being always on the 'easy' curve, you can do that s well.
