I still go to those caves out of sheer habit but I find VoG Heroic is survivable without hiding once there's no 29s on the team.Hard Vault, still about an hour, it still has a lot of waiting around and people swapping in and out of characters to get the chests
Bosses fall a little faster but the oracle ice breaking still takes the longest and waiting in the cave for the conflux phases to end sometimes take forever.
