A few notes on your team. You should not die here on any trash pull with 3 mages. If you haven't already, set up some system to assign a target to each mage and have a sheep key to spam on pull. I use target for DPS with a seperate assist macro to assign DPS target. I use focus for CC, so I have 2 buttons that on my tank assign a raid icon and each mage has a /focus macro on only one of the buttons (I have show party's targets turned on so when they /target and /focus I can see in group window quickly if they have the right one). During pull shift + main dps spam key = sheep for mages (modifiers are on extra mouse buttons), so my tank does his rotation on his target, my mages sheep, and my other dps does nothing while I'm spamming it on pull.
I have similar sort of setup, set focus on mages before the fight and then cast sheep on focus target. Had it all down pat by the end of the instance, after i learnt that the destroyers change target when they knock u in the air so need to have righteous defence ready to go before u even land.
Regarding the second boss. Buff shadow resistance, use sr aura (if they stack) and mage armor and nuke away on the boss _without_ the pala standing in melee range. If nobody is in melee range then he will only shadow bolt some of your guys but not start to melee anything. Should be easily healable by the priest since you can concentrate on single target healing. Just pick up the felhunters with your pala and you should be good.
Ahhh excellent idea, i only run ramps once so far so didn't really try many tactics after i managed to scrape through, but definatley sounds like a much better way to take him down than what i was doing!! Thanks allot ill give it a shot tonight and post some results tommorow.

I'd activate fire ward (or flame ward? the fire dmg absorption thing), mana shield and mage armor. That + fire resistance aura from the pally should help a lot.
Also, if you're perhaps not used to spreading out yet then do it. You really don't want everyone standing in one spot for this boss.
The dragon boss is stupidly hard without some 'good' gear for your tank and healer. You want enough hp on your tank to survive if the healer has to heal someone else, and enough mana regen / mana on the healer to actually heal through all that madness
Yeh i completley forgot bout mages fire ward buff. Ill do that tonight and see how i go. Also i picked up a few cheap fire resistance items from the AH so ill put them on aswell as use some fire pots (and pallys aura). I also will try the kiting option that Phara suggested as it sounds quite viable imo. Just wanna kill the dragon so i can complete the ramparts quest.

Just watched the movie posted by Schwarz and i didnt relise that you could dps the dragon down while he is in flight!!!! look like it was much easier than doing it the proper way, think im gonna try that first as it seems as tho you skip the whole fire thing.

In Regards to my setup this is how i role at the moment

Shift 1 - 7 (whatever my fingers can stretch too :P) = Mages (Fireball, Ice block, Pyroblast etc.)
1 - 7 = Pallys keys
Direction Arrows = Set mage focus
Shift Q,E,F,G,C,V,B = Mixed mage/priest combos (the "oh shit" buttons really, eg: shift v mana shields mages and priest bubbles self) (Shift + E = instant cast mage spell cant remember the name) but ya get the idea anywhoo

For Healing, i use an addon called Clique and Hotkeynet's mouse hook, so basically Shift Rclick on party member on main and priest will heal that party member. So i got Shift Left Click to do greater heal, shift right click for quick heal, alt left click for priests bubble and alt right click for renew

P.S: my gear is pretty fail but if anyone notices any items which can be upgraded easily through questing im more than happy to hear suggestions. (Obviously im aware of the ramparts quests for gear :P )

Like i said earlier i will try again tonight and repost tommorow to let ya all know how it went. (maybe we should add to the duel boxing wiki to include some of these suggestions, espcially the vid of dps'ing the dragon down before initiating the fight, if it works as easy as it did in the vid then thats definatley the ezmode)
Thanks allot for every suggestion, greatly appreciated.
