Competitive PvE exists too (speedruns, world first races, etc). In FFXIV mods are less tolerated and while some raiders use triggers (TTS voice lines triggered by enemy actions or friendly buffs to tell you what to do), many consider it borderline or actual cheating, while others are fine with it because it's similar to having a player do it (ignoring perfect accuracy and no brain capacity used). So it's a controversial area.
