Want to push the gear a bit more

[Darkscourge]

Hey all. I just started tanking ulduar 10 with the guild the other day and was very happy with the results (thanks to tankspot members). I just want to know if anyone could pick up anything on The World of Warcraft Armory (http://www.wowarmory.com/character-sheet.xml?r=Barthilas&n=Darkscourge) to help with survivability. I am very happy with my threat generation and my dps is very high for a tank imo (well into the 2k area)

p.s i use Rhinolicious Wormsteak - Item - World of Warcraft (http://www.wowhead.com/?item=42994) to push stam up and also puts me at 23exp (bit short) and also use Flask of Stoneblood - Item - World of Warcraft (http://www.wowhead.com/?item=46379). usually with all buffs etc i hit 40-42k

the only thing i can prob suggest is get the sigil that gives u like i think 200 more dodge or something like that for 20 secs, that can help u avoid more hits and allows u to get more RS to use it and try and get constant avoidence buff
