There is an ocean of QQ about 4.1 and the difficulty of Zul'Gurub and Zul'Aman all over the place, Trade chat is flooded with Blizzard hate and even a few guildies who tried to PuG the new dungeons were utterly disappointed. It reminded me a lot of the way people were flipping out when they hit 85 and tried to run heroics and got their faces carved up and yes, I tried to PuG it on Tuesday night and also got my face carved up a bit when the healers could not keep up with the damage. I shrugged, dropped group and determined to go back with a guild group.
I logged in last night to see Thistle having gone through trying to heal four tanks over an hour in Z'A and unable to get past the first trash pull. So, we had two other folks who wanted to run and we grouped up and hit the random queue, picked up a warrior who seemed pretty stable and started pulling. It was slow and careful going, we were all on vent and were communicating actively as we pulled and not really knowing much about the bosses other than a quick glance at WoWHead for abilities and man, it was a blast.
It took about an hour but it was fun to improvise and react to abilities as they were happening. The warrior we PuG'd was also really patient and worked with us as we chewed through the pulls and bosses without any problem. As we got to Dragonhawk boss, we wiped a couple of times on the trash but after that we quickly got through the next three bosses and were facing down the last boss. One more wipe to get a handle for the way he was pulling the totems and then he went down easily enough, so of the three total wipes in there, two were due to accidental roaming patrol pulls we missed.
Having cleared through Zul'Aman in about an hour and change, we hit up Zul'Gurub for another hour which was all the time I had left, and other than the Snake boss, I thought the rest of the instance was significantly easier than Zul'Aman though we did wipe on the Panther boss until I figured out the rate of puling adds. We wrapped up all but Jin'do when it got to be about 1 AM and we called it a day.
I'm not saying all this to brag, I'm suggesting that the first couple of times you go through the new dungeons - take it slow, pull carefully, use CC on pulls and treat the dungeon with just a bit of respect and I promise it will be a really, really rewarding experience.
Almost every pull can be CC'd and we used it liberally to ease the rate of incoming damage. Stuns and interrupts are your friends. Even with the amount of time talking and CCing we took, we still wound up killing Eagle and Bear within the sacrifice timer - I imagine we'll be doing bear runs in a week or two.
So, yeah, if you PuG and the people aren't ready for this content, you will have pain. But you can take the lead, ask for CC, make sure the healers and tanks are communicating actively to survive and manage the incoming damage (this is a good amount of incoming tank damage and my cooldowns were always ticking) - and this is doable.
This might sound like elitist talk, but honestly, do it now before it gets nerfed.
The experience is fantastic. I promise.
