Maybe I'm Too Old Play WoW

So we were running Gruul's Lair last night, and I was having a tough time not dying during the first Ground Slam -> Slow -> Shatter sequence. I know how to keep myself alive in most situations in the game, but in this particular encounter, you have to make sure that you're not near anyone, or you'll take damage that multiplies by the number of people who are around you. It's not fun.

I could never seem to get far enough away from enough people to not take serious damage or die. And I was suppose to be spam healing the main tanks all the while. Now, it didn't help that one of our rogues Cloak of Shadow-ed out of the Shatter, ran right past me, and killed me one time, but even in good circumstances, I had a tough time staying up and doing my job.

I think that part of the issue is that I just never developed those uber-fast gaming reflexes, and that when I play WoW, I tend to focus on one task very intently (like, say, not letting the MT die), sometimes to the detriment of the health of my characters. Mutli-tasking generally isn't a problem for me (it can't be, given what I do), so fights like this are right tough. It makes me feel all old.
