I've just finished doing Ramparts,

60 pala
60 h priest
60 f mage
60 des lock
60 s priest

First boss was easy, dots then nuke.. when healers were going to heal i aoe silenced, he then died.. and i finished off the healers.

The demon guy was hard until i realised the curse aura was an ACTUAL curse.. and not matter how far i was from the boss it didn't matter! so once i realised i could decurse it I killed him easily... though i did manage to kill him before, after losing my casters to the aura.. my healer and paladin took down the last 150k life!

Dragon.. got it sussed now. Casters all in a pile and I set my arrow keys to strafe left right / move fwd backward, Then I keep an eye on them and move them out flames.. whilst i constantly heal paladin tank and nuke! Keep my tank moving around the dragon most of the time, so not to stay in hot spots.

No problems with trash.
