DT is a fun place, I miss doing it. Best parties are 2 tanks, cleric, 2 DDs or tank, healing cleric, clanking cleric, and 2 DDs. I'm sure it's changed from when it was 85 - 100levels. I know they cut the power of the mobs quite a bit. My favorite times were duoing with a fighter friend and taking out the dragon, and when I was in a party with 2 fighters, another cleric, and a mage. One fighter left, they had me clank the dragon while the other 3 took care of all of the side stuff. Epic fun!
Oh, and Hessah, watch out for those stupid potatoes, they can occasionally use a move called blind shot - your entire screen goes bright white instantly, then slowly fades to normal. In the meantime, you become disoriented and get a quick headache. The 2 times it happened to me, I had to go AFK and clear my head before I went back to playing.
