Changes to underground dungeons

I think these changes to these dungeons are a very nice addition to the game
A friend and I were able to duo through these dungeons with very little resources
We both had +3 lv1 equips, all pieces and some basic buffs. (Granted, it is unusual to have ALL pieces on you, but average 160+ player has better than +3 equips :D )

There's 4 difficulties to choose from.
Difficulty 1 being easy, and made for 1-2 players
Difficulty 2 requires either a very skilled and well equipped player, or 2-4 players with average skill and equips
Difficulty 3 is slightly tougher than current difficulty on live server
and difficulty 4 requiring a full party of coordinated and skilled players, as a small mistake can get you killed very easily

But as the difficulty goes up, the dungeon holds stronger rewards :)

So far I have 7 videos about these dungeons

Here are some videos showing the new boosted war kahuna in the new PP underground dungeons:
