Well, whether or not the stuff to them has any use to them or not is not the point. Some people aren't all about the stats. I do wanna look cool while fighting ( personally). If end game gear has the best stats in the game but it looks like crap, why would I bother putting on something that looks hideous? Sure stats are good and are needed to progress through certain content, however, you don't need the best gear in the world to get past a lot of the content.
Gear is progressing for something you strive for. Primals/Dungeons are Content. Personally if you play the game for just the gear and not having fun playing the actual content, then at some point, you will hit a point where you got the best there is and now you are telling yourself there is no content based on what you accomplished.
I agree that how they are handling the progression towards gear is a little weird. However, I still feel the gear doesn't make content fun, it's something you strive for in the end result ( hopefully). The content should be the one that gives the average person fun things to do.
Gear is part of the game no denying that but this is how I feel as a whole:
1) If X content requires you to have ilvl 70, then get gear for that content that is ilvl 70 or higher
2) If you can beat the content with the gear you love to wear, then you should wear it.
You are only looking at the content in a progression of gear sort of way. ( which if you have that mentality, of course the game will appear as if there's nothing to do).
If you take out gear from the equation you'll still have all the content available for you to have fun with.
I won't deny the fact that getting gear you want from content is an awesome feeling and will want the gear that will make my character look badass. However, I don't judge content based on gear. I judge it by how the content play, is it a fun content to do etc etc. This is my mentality when playing any game, and I have fun doing it.
I hate the FATE content but it gives the best seals at a fast rate, but I do GC leves because they appeal to me more.
Let me ask you, is the actual content itself fun to you?
Also to add this is a MMO launch, if you were honestly expecting more than what they gave, then you really got your hopes up.
