Enemy diversity is just part of another big issue for me: General gameplay diversity. Most of the stuff the game has you do outside of story content is just fighting the same enemies or boss types. There's no unique dungeons or bosses, the "domains" you need to farm for gear are all just waves of enemies, daily quests are just killing enemies, etc. There's rarely any unique mechanics or novel ideas that actually change the way you play, which makes the game get stale fast.
