The thing that I keep seeing is that people seem to think that once you hit level 80, PvE is over with in GW2. That couldn't be farther from the truth imo.
I sort of see it like how level 20 was the max level for GW1, and it was easy to reach that level cap after a few short hours of playing. That didn't mean that the PvE content was over with since you still had the rest of the gameworld and storyline to discover and finish up and that wasn't short by any means.
GW2's 80 level cap isn't as easy to reach as GW1's level 20 cap is, but in some regards I feel it's sort of the same situation where there's still a lot to do PvE-wise such as 100% completing all the areas, finishing all your personal quests, grinding to craft those shiny legendary weapons, doing all of the dungeons and then doing them in exploration mode. Reaching level 80 doesn't mean that you've done everything and seen everything in PvE.
While in the overworld map there can be a lot of zerginess, I feel that Explorable-mode Dungeons are where it's at when it comes to satisfying those who liked being in a tight-knit group of party members overcoming a tough raid. In this case though, there's only 5 players instead of 20 or more. There isn't a strict "Holy Trinity" definition to builds in dungeons, but builds still DO count for a lot in explorable mode. You can't just run through with glass-cannon DPS builds for everyone and fully expect to last long.
I ran through Ascalonian Catacombs (Exploration Mode) with PUGs and it was just awful since people just used their PvE build and we kept dying because there was no direction and no synergy with our builds. Later on, I got my guild members to do AC-EM with me and it was a completely different experience since we had me as a heal/blind-burning Guardian, a flag-buffing banner/greatsword Warrior, an aoe Elementalist, a shortbow Ranger, and a aoe condition Necro. This made such a difference in that our builds were diversified and aimed towards control and support. I think we all died and had to run back twice but each time we learnt what we did wrong and adjusted to overcome it. It was satisfying as hell and showed that not everyone can simply build whatever they want and mash buttons to beat things in GW2.
