I'd like to see both more open world dungeons, as well as instanced ones.

I think some other level 25+ instanced dungeons would be fun, along with one or two level 35+ one as well. But with 2.0 later this year, I think it would be great if we got a lot of this content added around that time.

I'd also like to see instance dungeons that didn't have a time cap on them, not that the time cap should be removed in all cases. But perhaps a good solution would be to add a difficulty selector to the dungeon, where the low difficulty removed the cap, or set it to three hours or something large, that way players could explore the dungeon and not try to speed run it. Then, when increased the time limit decreased, as well as mobs got harder. (just a thought).
