Personally, I’m not up high enough to be doing Karazhan, but the Guild Relations Forum on the official World of Warcraft forums has some great discussions about it periodically and I thought to share.
Healing Beyond 5-man Dungeons
These days, as level 70s working together with their guildmates to progress through tough content such as Karazhan, Gruul’s Lair and beyond, there’s a lot of learning that every class needs to do in order to perform well enough to allow the whole team to succeed.
As healers in The Burning Crusade expansion, one of the biggest challenges is in learning how to work in conjunction with other healers in the raid so effective and efficient healing tactics are used, resulting in less overhealing and less wipes that come from two healers healing the same member while another one dies.
The Burning Crusade’s Sizable Challenge
One of the biggest challenges that a lot of guilds are facing with regards to healers learning to work together is the simple fact that a lot of the level 70s that are raiding the “End Game” content right now weren’t around for the “old End Game” and it is acknowledged by many that the challenge jump from Heroic 5-man content to Karazhan is way bigger than the jump from, say, Blackrock Depths (BRD) to a 10-man Lower Blackrock Spire (LBRS) run was back before the expansion came out.
Sure, in the old days there were 20 and 40-man raid dungeons such as Zul’Gurub and Molten Core and Naxxaramus, but it’s widely agreed that the challenge progression and learning curve of the pre-expansion End Game was more friendly to the process of gearing and training up inexperienced recruits.
Healing Strategies and Styles Change Between 5 and 10 man
A secondary challenge that exists for healers new to the raiding game is that the strategies used when one is the only dedicated healer in the party are quite different from those used when there’s two healers dedicated to the party.
