Go play Monster Hunter, it'll blow your mind! The entire point of the game is getting better gear to get better gear lol.

That's just how progression works in video games. You get better gear, skills, abilities, whatever so you can keep progressing through the game to get even better gear, skills, abilities, whatever. That's how video game progression works, until you get to the end of the game. The only thing that's different in MMOs is that there is often higher tiers of endgame stuff to aspire to. If you've got a problem with it then MMOs are likely not for you.
