They do. The problem is that this game is a gear-farming game. If you can just buy all the stuff right away then everything else is pointless.
If you're asking if it's a "grind for the sake of grind", yes. That is exactly what it is. Welcome to MMO gaming.
What I don't understand with this approach is that it simply doesn't work as it's implemented in this game right now.
You come across a lot of ''nothing to do'' threads on this forum, and I think the answers to this question (excluding ''you are right, game sucks'') generally fall into two types: you have people who either reach the end of the grind or give up on it, and conclude that if you stop caring so much about acquiring assets, and just enjoy the game, missions, fights, the world, in-game events, player encounters... you can get a pretty good experience for a long time. You also have people who laser-focus one object and center their playstyle around this. Often it's based on meta/community which tells a lot I think... examples of this is secret chasers, people who explore for screenshots, fuel rats, BGS warriors...
What I mean is that I don't understand how the big grind in any way keeps the ''nothing to do'' feelings at bay. It's not 2003 anymore, most people recognize the hollowness of hamster-wheel game design and recoil from it. You don't seem to be very enthusiastic about this approach yourself, you mostly seem to think it is unavoidable?
In your signature, you claim that any video game will feel ''gamey'', because it is a video game. Do you really believe that? If so, I would understand your attitude, but I think that you are terribly wrong.
