You're a low-level, and you're still in ARR content judging by your main job's max level. ARR wasn't the high point of the story, and combat is geared for endgame not for leveling. The game could be better about the pacing of players catching up, but I don't think they'll do that because they have Level Up potions and Story Skip potions on the cash shop.

Have your criticisms of the game, but the devs certainly do not hate it; they clawed and fought to bring it back from the brink that was 1.0.
