Why you should play a healer!

[Cynfael]

Things are easy for everyone when the going is smooth. The experience or inexperience of a healer shines bright when something decides to toss a wrench at "cast cure, repeat. Big pull, cast cure, some oGCD, repeat."

You aren't wrong, but it's also true that healing tools are incredibly powerful and that the healing Jobs themselves are mechanically simple. Personally I experience very low stress as a healer except in the odd situation you describe, where everyone else is conspiring to make your life difficult by failing mechanics left and right. Even then, if they are doing so poorly that I'm challenged to keep them alive, I am at peace with their accomplishment should they actually manage to die.

For me I suppose it comes down to this: healer gameplay is the most forgiving and least stressful in execution (even for a true "ABC" healer), but other players are more likely to be a source of stress since they may be inclined to blame the healer regardless of where fault actually lies. If this happens to a player frequently enough, or if they are fairly sensitive to criticism, the healer role could become stressful pretty easily.
