Aggro indicators: Nah, plenty of games have aggro indicators, and not every mob that is aggressive looks aggressive.(vultures, roselets)

Raids:I think raids were already planned from the start judging by the NMs they released, but almost everyone has raids these days, I guess you could bulk the norm and put in something else(like uh....) but there's definitely a consumer base for raiding.

Instanced dungeons: I understand they break immersion, but so is fighting another group for the first attack on this ancient and terrible evil you're supposed to be vanquishing, then watching them vanquish it, then waiting for this ancient and terrible evil to respawn.

Meaningless quests: ok yeah, meaningless quests suck.

Exclamation points: I could talk to every npc in the city once and if they have a quest that is above my rank I would never know unless i went and talked to them after every level, sure some quests can be hidden but it'd be less annoying if there was a REASON for them to be hidden.

Auto attack: I never liked auto attack but I can see the reasoning behind it.
