I just did the daily vet dungeon with a group we had v14 v15 and 2 v16 ( me one of the v16) we set it to v16 everything was v16 but when we kill the first boss he drop a v14 purple dagger we thought this was weird cause the boss along with everything ESLE in the dungeon was v16
Dungeon Scaling
Every Dungeon now scales up to Veteran Rank 16 which will allow items, such as Monster Masks, to drop at the highest achievable level.
That is what the patch notes say but items only went to v14
P.S. I got the dagger and I am v16 but the dagger was only v14
