Like the title says what dungeons would you like to be revisited, and all those who say revisited content is crap, just tell us the one you would not mind so much. Raids can be used also. If you have any ideas related to new lore or mechanics, feel free to say it.
My personal choice is Scarlet Monestary (I think I mispelled it but w/e) The looks and theme with the items possible is great and there has not been any endgame content related to Scarlet Crusade/Onslaught. Of course, I hope we keep some of the old items and bosses e.g. Scarlet Tabard, The Ravager and Herod`s Shoulder. For new bosses, we could have just some bright new scarlet leaders and a darker force behind them.
Tell your favourite and discuss about them!
