Or, Amber States the Obvious
As usual, this will be mostly holy-pally flavored, with some disc priest ponderings mixed in. But the UI tips work for anyone!
The key to being a success healing the Kel’Thuzad fight is a simple one:
Use Holy Shock. And more than that: use it at the right time.
If HS is something you use a lot of, learn to hold off, and watch for the FB cast. I’m normally assigned to the tank/off tank, but one eye is always on my chat log. As soon as I see the alert, off goes HS. I leave the topping off heals to other healers, but that instant heal is priceless.
I was lucky enough to be healing our first couple of KT deaths with a disc priest and a resto druid. While a Flash (of Light OR Heal, for my priesty friends) is quick enough to save FB’d folks, the instant nature of HS and Penance are too good to ignore. Use ’em and abuse ’em, and it should help reduce deaths from lag and other unfortunate mishaps. Squishies, don’t forget your bubbles.
Another important key is: know who the fuck to heal, ASAP!
In 10 mans it’s a sight easier-after all, it’s a much smaller group to look through. But most UIs will let you do custom highlighting, and this is really what you need to suceed. For more on this, check out Penance Priest. I use X-perl, which does allow you to use custom highlighting…but uh, I can’t get it to work. I’ll play with it some more, but in the meantime, DBM throws marks up on the affected members and I can see those on my raid frames just fine. Looking for the skull is easier than looking for, say, Sidearm the Nubcake Critchicken.
