First off here is a link to my armory page:
The World of Warcraft Armory
Also out guild currently has Kara on farms (2 groups doing full clears every Wednesday), High King/Gruul and Magtheridon more or less on farm. We also currently have the 3/4 of the first bosses in ZA on farm and are trying to get Jan'Alai and Hex Lord down more often but I normally get subbed out for a dps warrior to help out on the dps.
I occasionally fill in as main tank when our current one is out and lead our second kara group. There are a couple other offtanks that are about as geared but I always seem to do a better job then them.
I know I need a couple upgrades in my current set (helm, main hand, and ranged mainly) but I seem to be unlucky on drops and a bit short on gold for a couple fancy things like the Khorium Destroyer.
I've had priority on the tier 4 helm if it ever drops but the past 3-4 weeks it hasn't and same thing with the Kings Defender and
Sun Eater. I know you need to get a bit lucky on drops to get anything but is there anything else I may be overlooking that may be upgrades to those slots compared to what I currently have? Should I go for the badge helm even though I will replace it as soon as a helm token drops?
