I had a player in Castrum Lacus Litore last night who hadn't done a single class quest past 30 and was exclusively spamming Rage of Halone, all the while dealing less damage than the NPCs that accompany the raid.

Until they decide to create content in the leveling experience that actually holds players to a higher standard, tuning content to where dead weight cannot be carried would only make it infinitely more frustrating unfortunately. I'd honestly rather my Nier Raid be a 30 minute snooze fest than a 3 hour wipefest for irrelevant garbage loot.
