Alright I ran Gun'Drak again tonight and cleared all 5 bosses (Yay!). Not only that but when I did I got revered with Argent Crusade for the head enchant AND some nice shoulders dropped with extra stam. I also bought some tempered titansteel treads for the extra stam.
So now I'm sitting on ~24k hp, 535 defense, 17% dodge, 18% parry, 25k armor.
Eck was pretty easy. I wiped on the first try because I messed up with the taunting. I wanted to be 100% sure I owned him the second time so I dropped 4x earth eles which worked for AND against me... I never had to heal my tank, only had to chain heal on my shamans when he spit, but since the eles were all over the place every time he spit he would hit all my shamans. Wasn't that big of deal to heal through it (I had a nature resist totem down, not sure if that helped). Either way he was easy the second try.
The last boss wiped the floor with me the first time, and the second time I BARELY got him down. My tank was down, 3 of my shamans were down, my last shaman had 1k health and the boss had 500 health left and my LB went off JUST before his next hit otherwise it would have been another wipe. I think with the extra stats on my tank he will get easier now :)
So this will be my main farming instance now - all but the last boss are super easy (the first 3 bosses I've killed both times I've tried them without losing a single person).
