Lvl 76 Matrons!

It took a lot of work, but I got it done :D

Took a few hours to do the pvp part, AV was a real pain, lagging worse than dalaran, most people being geared lvl 80's, and racing the other hordes to the bunkers.

For UP, I first cleared to last boss in a regular group with my main, then went in with the shamans.
Only got him to 86% using just the shamans, since the 6 lvl difference made him kinda hard to hit, and he hits pretty hard (around 8k on my shammies, earth ele's died pretty fast too).
So I sat one shaman out and had a friend come on his geared tank, I just healed him, and we killed him eventually.
Then for the last shaman I cleared the place again on my main, then switched my main for my last shaman before last boss.

This way I even kept my XP even between the shammies :)

Grats! sounds like you put alot of work into it!
