MMOs in general, and GW2 in specific, have always had a little bit more in their DNA. Crafting, exploration, and socialization are all expected base parts of the genre, and GW2 in particular has put heavy emphasis on exploring via map completion and the need to find hero points to max your character, and platforming via Jumping Puzzles that can be found at all stages of the game, including the base game's opening zones. At the risk of sounding harsh, I feel like if you "just want to kill bad guys," as you put it, you are best off logging out of GW2 and playing a game like Diablo or a FPS that are very specifically about mowing down waves of bad guys with various weaponry and not much else, though even those will often expect you to navigate a map or solve basic puzzles.
