Then SE should have done two version of void ark, normal and hardmode. Just scale up the damage and healing required to clear the instance. Make failed mechanics actually wipe the group. Bamn, hardmode without a huge amount of dev time required. Put normal in DF and make savage only enter-able by a premade group. The hardmode versions of the reward could be 210 (nothing special in the current meta) and the gear could be dyable. The rest of the rewards would be the same.

Casual players can have their snooze fest and players that want content with teeth could have it. This solutions literally takes nothing away from any player. It might take, what? Another month to retune void ark for hardmode? If that?
Honestly, I'd be very much up for this. I'm really itching for a progressive endgame raid. They could even make it an 8-man version or something that provides a lot of challenge for a single group. But that's just an idea.
