It's not official, it's my own metric.

It's just if you're not raiding, you're not being forced to play the class anywhere near it's fullest. You're not trying out new things to squeeze an extra tankbuster in your cooldowns, extra tankiness out of your existing cooldowns while pushing your DPS to the extreme.
And A5S is so easy these days (and when it was released), clearing it isn't much of a challenge.
