For Void Ark, just have all the chests appear at the end. This would heavily deter people (i.e scummy bards) leaving like assholes when their precious piece doesn't drop, then at the end, everyone has a fair shot at the loot, done. A token system would make it easier to get loot, but would also likely kill the content faster when people get what they want and never go back.

Also, I would welcome tougher 4 man dungeons, I barely have to heal outside of big pulls in the EX roulette (as a SCH, I can just make the fairy keep the tank alive for nearly all boss fights) I would welcome any sort of healing challenge outside of savage raids (last boss of the Vault and A4 normal are decent enough checks for the average healer)

I am surprised people are flipping out over a cat ear hood when there are already cat people in the game (complete with cat ears)
