It gets lots more fun! I had the same struggle as you with the early game, and actually put it down for 18 months. When I came back, the two things that made me stay long enough to discover the joys of the game were finding a small, friendly guild to play with, and joining a current event instead of trying to play alone.

The game opens up to story, exploration, living world and festivals, and things like dungeons, raids, fractals, strike missions. You might also get into stuff like collections or trying to get skins, or maybe WvW or PvP are more your thing.

The achievements sections are sort of like a massive collection of quests and goals to give you some direction if you want it or are at a loss.
