Guild Wars 2

I wonder if HoT will feature some new dungeon. I know that arena let
would like to stay away from dividing players true instancing, but still
i think that dungeons should play at least some part in HoT since its
a great way to introduce more chalking gameplay and bosses than the
world. For instance 5 players do coordinate more easily than a group of
50.

Agreed.
I was surprised that they mentioned nothing of new dungeons or anything dungeon related on their big announcement page.
That’s usually the first thing I see on an expansion page.

and dungeons are the only thing that will never get old, you can always come back with a bunch (4) of friends and do it.
The metaevents are cool, but if in 6 years not enough people is playing, you wont be able to do it. For the long term you need instances, or you wont be able to play.

I Really like to dungeon whit my friends, plus they could do some really cool hard stuff like whit FoW and Underworld. I just hope that Mordremoth won’t be a dungeon boss, well at least not an easy one like Zhaitan
