The elimination of res rushing is a great change, imo. However now that its been implemented there’s no reason i can think of that there can’t be more waypoints in dungeons. Having to trek 5 or 10 minutes after a wipe is a waste of time which is no longer necessary with the elimination of “res rushing”.
Every challenging boss fight needs a waypoint preceding it (lupicus) or at the very least dungeons with few and far between waypoints need a few more, twilight arbor is a very good example of this. If you somehow wipe in twilight arbor its a long and hazardous trek back to where you died.
