I just 5 shammied almost all of MC. I can kill everything in the entire instance with the exception of baron geddon as he will put a magic debuf on you that burns 400 mana every 3 seconds. I skipped him and killed everything else, then brought in a DK tank friend, and it was ridiculously easy, but I was forced to wait 5 minutes for the debuff to wear off. With water shield and all mana totems, I could barely regen any mana even out of combat. I wonder if something like restorative potion would work to remove the magic debuf. All the other fights where a simple dps race. Kinda funny, he got knocked back by ragnaros rather quickly and died in the lava, and I was still able to burn him down from 90% well before he submerged.

Gehennas was one of the tougher fights as the magical debuf puts cripples your healing by 75%. I could have let a few of my shammys die, but I managed to live through it. Garr was a little challenging as you can either try to kill the adds first and get knocked all over the place, or just ignore the adds and focus garr down. I was focusing Garr, but using my magma totems and got knocked a few times all over the place, but still didn't even come close to dying.

I had a few wipes due to stupidity and some for forgetting the fights. Golemagg, I was trying to remember how to split up the corehounds so I could focus him down, but realized that it's nothing more than an easy dps fight to simply ignore the adds and burn him down. Sulfuron Harbinger was surprisingly easy - especially with lava burst as you can usually nuke the priests down at 50% before the others start to heal. Same with Domo - focus the healers first and try to keep an eye on the spell reflect debuff and just got to town.

After that experience, I think I'm gonna continue to farm it weekly until i get either the twink healing (+29 SP) or the spell (+30 SP) enchant. I got 5 boe epics that all sold for over 100g
