I can agree with the OP, the game does limit at a point in time, the dungeons become useless once you grind out a set you want, the cosmetic feel is not enough to satisfy the thirst of players, but now once you get a set even if yellows drop all you can do is salvage them or sell them on AH ( which most people won’t even buy anyways ). The game has a lot to do but at one point it becomes a cycle of the same stuff over and over, but thats the problems with mmorpg’s there will never be so much to do that you will never run into a cycle of content and a lot of the 80s we see now burned so much of the content so quickly in mass amounts it’s no longer fun anymore. This is a problem with all mmorpg’s in general, but to me the game is great for what it is, and we should be getting more content put into the game soon, as more people get 80 or close to 80. So hang in there and just either take a break and just do dailies and WvW or just stay off until new content is put in.
The problem with most people is you want 5 pieces of rare armor or some crap with the chance of an exotic with huge amounts of silver and karma for running an explorable mode. Wake up, get this WOW sense of mind out of your brains or what ever past mmo’s you played, this is GW2 they are doing it different and working on making stuff in their eyes and many of the players eyes good rewards and harder challenges.
