That said, if we're talking strictly normal or pre-bone storm heroic, then, yeah, standing in front of the boss MIGHT make a difference. I don't know that Marrowgar actually has a cleave, but he definitely drops fire in front of him, which may serve the same purpose.
I 2 man it with a ret paladin as a MW monk, i'm half heroic geared and he's full normal; It's not really that big a problem anywhere as there's ways to bypass a lot of the mechanics (e.g. on LK if every player has an add (or the boss) hitting them, nobody will get picked up by the valkyrs). I guess if you're having trouble with dps on deathwhisper that may be an issue, but then you could just solo it (if you're the right class).
But she does MC if there is only one person still. That's the point I'm trying to make.
OT: I was able to solo most of ICC 25 normal as an enhancement shaman (Had to switch to Ele with my lock friend for help on Valithra, and get his help on Blood Queen; I wouldn't recommend offhealing Valithra on heroic, it took a significant amount of time for me on normal) so if you have the DPS to beat enrages I don't see why a warrior/healer couldn't do it. Just Lich King will be a pain cause you'll have to solo kill three Val'kyr in a row to make sure your monk doesn't die. Or push the second transition before the Val'kyr spawn, which means danger from frost orbs during the first transition.
Aside from that, shouldn't be too bad.
Frost orbs can be cheesed, but you can't pull Lich King up the steps. As a Warrior, ranged DPS is pitiful, and Lich King transitions in the middle. So if you don't want Val'kyr, you can't be on the steps.
You can kill deathwhisper before MC, but you won't do it as 2 unless you're both dps in hc gear. Done it as 3 before and that was tight
You don't need to worry about valkyrs on lich king - just make sure each additional person in the fight holds onto a spirit. As long as you have aggro on a spirit valkyrs will not pick you up. On top of this, frost orbs can be easily cleaved down or 1-2 shot, killed with pets, etc.
I forgot about having a raging spirit attack me, but the valks all want to pick you up, after each one drops you the next picks you up, so I had the paladin move Lich King to the platform edge and after third drop I shadow stepped

Then we discovered the 10-man save -> switch to heroic thing. We haven't done anything else but LK25hc every week since then. ^^
Two people will have the DPS, but mechanics can be troublesome. I've had issues with the MCs on Lady Deathwhisper and lack of people to bite on Blood Queen without enough people.
Also really the fights just take obnoxiously long compared to just grabbing one or two more friends.
So much misinformation in one topic.
You could have and still can.
Clear everything on 10 man normal, go out. Swap to 25 normal, go in. Swap inside to 25 Heroic.
Damn, it's 25 heroic and lich king is there. I did this even last week, so definetely still possible.
Much love to Indicate for creating. Eis' work
