I am currently co-leading a casual raid group in our guild. We are doing very well in Karazhan (almost one night full clears; one-shotting most every boss). The other leader and I are both tanks and are currently battling for the MT spot. Both of us have discussed the possibility of moving onto ZA.
Now onto the questions:
Who should be the actual MT? According to tank spot, I have more EH then he does, but I know armor and avoidance plays a part in some boss fights.
Being that we are both warriors, he has made it known that both of us can't go into ZA together, and I agree to a point, but I know that I am getting screwed over in the process, because he has declared he is tanking.
I also would like to know what minute upgrades I should get (currently working on getting the belt and legs from Kara or 2.4 badge gear) and I'd like an opinion on my sockets and enchants.
Here are the tank's armorys:
Mine: [With the correct trinket on and without buffs, I have 15964 HP and a few more percentage points in parry and dodge.]
The World of Warcraft Armory
The other tank:
The World of Warcraft Armory
I also forgot to mention that I have close to 41,000 EH and he has close to 39,000 EH.
