Low Level Dungeons: Speedrunning is not cool with lowbies in the party.

[Seryl199]

That's not the point. The point is that dungeons from 1-49 are for leveling and gearing, unless you get a fresh party member that actually needs it for quest progression, so choosing to pass up mobs, especially without asking the party their preference beforehand, is disappointing particularly for ranged dps that have long queue times.
