There's literally nothing difficult in 24 mans.
You have 6 healers in the whole raid, 3 tanks, and 15 dps.
With how popular RDM is, there's bound to be one or two RDMs in there in addition to 6 healers.
That's SEVEN rezes

You basically can literally just watch Netflix and press Glare every 5 seconds like the rest of the people who do them and you can complete them.
You just have to follow the crowd to figure out where the safe spot is.

Run it, give it a try and you'll see that some Dungeons are a lot more punishing than 24 mans, and some of those Dungeons are required to progress MSQ. Non-Savage/Ultimate content is designed to be able to be completed with the minimum effort possible.
