Undercity + Rootholds mechanics need to be combined into NMD. We don't need 3+ extra dungeon game modes.

I like Undercity. Choose what I want to target and run it. I could take or leave the time mechanics inside Undercity though, they are just a formality and don't pose any sort of challenge currently.

Rootholds mechanics from Hordes is ok, still needs improvement, but I can see potential with it and at least would make NMD'S more interesting.

Regular dungeons...really are pointless to me at this time. Don't think I've run one that wasn't part of the season quest in the last 5 seasons.

Introduce NMD with the Undercity Tribute mechanics early on like lvl 20 or so, and then the Roothold mechanics at 60.

NMD + Tributes + Roothold/IH mechanic = Win
