I do think those statistics are not totally representative as there's a lot of padding potential in NH, for example taking purely anecdotal evidence from tichondrius split raids last night, our spriests alt (a boomkin) beat my rogue by a good chunk on overall damage, however he's starfalling and dotting the bloods in order to kill them off while i'm tunneling the boss.
https://www.warcraftlogs.com/statist...metric=bossdps - if we look at boss damage (which is the area feral competes in) Feral is middle of the pack, in a position which could probably require some loves but without the hyperbole of 24 OUT OF 24 WE'RE THE WORST SPEC IN THE GAME AAAAAA.
