This past weekend I was helping a friend of mine run MgT on my he needed a dps'er so I jumped over to my Ret pally. Joined the group and saw we have a pally tank I was thinking that this would be a easy run. I was WRONG! I inspected his gear when we all got summoned and this is what I found.

He was tanking in PvP Ret gear. Now I have seen some pallys tank in PvP a few peices of healing gear on the lower lvl outlands instances where you will not take much dmg. So the added mana and spell dmg. makes for a quick run. But a pally tanking in Ret gear, I didn't understand it.
But I was willing to give it a go to help out a friend buy the time we got to the third boss we had wiped about 6 times. He could not hold aggro on any mobs and never used his concecration.
Now me being a pally tank also seeing this made me SICK! I run that place on my tank and never have a problem most of the time we can clear it in just over 1 hour with a decent group.
I ran into another pally tank that had no idea what he was doing. I was on my 48 warlock we were running ST we get down to all the dragon mobs at the bottom and we pull the fist set his health gets low and what does he do he bubbles, and we wipe. So we run back do the pull again and he does the same thing, I tell him don't bubble you drop all aggro and we die. He tells me "I was healing myself." so I say "That is why we have a healer in the group to heal you." We start another pull it starts going bad so I run around a corner and hearth and drop group.
I was very fustrated with the 2 pally tanks I ran into this weekend.
