Erm..my DNC worked perfectly end-game..in all areas, even Delve. If by weakness in end-game you meant at 75 cap when it initially released and didn't even have it's Mythic weapon/skill, I agree since that's what it sounded like you meant when you stated the support job brought more. Heck, Dancer was actually one of the perfect roles for Delve considering how alliances split off to tackle it lol. So while true it excelled low man, like any job in XI, those horrible at it makes it seem useless in any regard.

For example Blue Mage was HORRIBLE end-game and almost no one wanted it...why? Because of all the Bludgeon only Blue Mages end-game. Now Blue Mage is everywhere lol. So in all reality, the only thing DNC would need for this game is a few more offensive skills, Steps were nice but still needed a bit more.
