Some of you DPS'ers need to realize that you aren't so critical that one misstep means the doom of a pull. Is it ideal, no. Will your parse suffer? Most definitely. But it's not the end of an attempt if you don't have perfect uptime on a buff, or miss refreshing a debuff by a few seconds. Sure, miss timing a major buff like Trick Attack of Battle Litany definitely hurts, but then again healers also have to consider this with things like Chain Strategem and Card Buffs.

Parses don't equal content completion.

But again, I don't know why you all are so hung up on making strict comparisons in difficulty to the point of trying to imply healers are getting carried. And we wonder why there seems to be fewer healers...
