I've officially hit this wall today. Yesterday I got my two exotic weapons and all my armors are yellows and have good upgrades in them. I logged in tonight and felt bored, didn't know what to do... joined a pub dungeon, did that, dicked around with the TP a bit, then logged off.
I could go for exotics on armors too but the upgrade in stats isn't that huge. I could go for legendary on weaps but it's just cosmetic. So loot-wise I think my character is set so the carrot has been eaten. It was crunchy, delicious, an incredible carrot, but it's been devoured.
I've only spent about an hour in WvWvW so I guess I'll try that tomorrow, but loot and having a worthwhile goal to strive for is really important for me to continue in a game like this. Cosmetic changes aren't enough.
I still have a lot of the map to explore, my world completion is ~50%, but I have all the gear I wanted and unlocked all the skills, so I dunno what to aim for next. I'd love to continue the story but after getting into the Order of Secrets I've lost interest.
This could just be a case of getting burnt out by playing hundreds of hours in a short time, I don't have a life and have basically been playing GW2, arguing with Nintendo fans on gaf, and going to classes, 80% of it GW2. Time to take a break I guess.
P.S. One other thing I wanted to mention is I tried leveling up an alt (already had a few around lvl 7-10) and had no motivation to do so due to the grind. I tried leveling a crafting prof for her but just couldn't continue after a few lvls, too grind and boring going back & forth from the TP to the station, then switching to the 80 and grinding mats in Orr to sell on the TP, then back to the alt and rinse & repeat.
