Every Quest NPC I have seen are literally drones that just stand around and do nothing most of the time. They really are useless and they don’t contribute to the battles unless they are able to tank some of the MOBS for you, but even then you would get swarmed by the other 3-4 MOBS standing around. Occasionally you will see them spam their first skills and RARELY their second and third’s but really, MOST of the time they just stand around and get killed by the vastly more superior enemy MOBS. Seriously, increase the AI of the NPC’s or make their DPS somewhat noticable, because it is ruining the gameplay experience!
Also the ingame text dialogue would overlap sometimes, this was apparent in the personal quest for the big event battles.
Is there a specific quest where the NPCs are getting overwhelmed? Changing NPC behavior is something that we do on a case-by-case basis, so if you can provide specific examples, we can better evaluate what we can do to improve their behavior. Thanks!
