Raid Rx is designed to encapsulate and cure the shock and horror that is 25-man raid healing. Ok, so it's mostly horror... Anyways, if you're a big fan of X-TREME Whack-A-Mole (or are being forced into it against your will) this is the column for you. In the spirit of pigeons, the picture to the right reminded me of the old adage "It's more efficient to rez you."
There are 9 classes that can dps, but only 4 that can heal. Warrior bandage sets don't count, sorry! While the raid damage doers are all about "providing massive quantities of steady and sustained DPS", you can often go it alone for the most part, assuming you know your place on the threat meter. Healers, on the other hand, have to work together as a team from the first pull to the last. Why? Because dps's damage stacks, while healing can cancel each other out. Gone are the days of Mana Conserve. /sniff sniff
Compounding the issue is most healers have only played their class into end game content. If you were crazy like me and rerolled a second healer when your guild was already on Morogrim, more power to you! But if you say anything that starts with "Back when my other healer ran <insert Pre-BC raid>..." then you prolly got my Mana Conserve reference, but your actual raiding experience of the current class design is low at best. Instead you're stuck reading the EJ forums and other references for classes you don't play. See Anonymous39857? That's me trying to read up on Resto Shamans.
So what does that all mean? You have 7 people with 4 different classes that have to work together while only ever played one class at their current content level. They might have the book smarts of what's going on around them, but no shoes that can be walked in. (Swapping chars is baaad for you and the raid, plus you'll go to Blizz jail.) Lots of commenters for my previous posts have offered their opinions on which class should be doing what and on whom. With all the interest in this particular subject, I wanted to put together something concise.
