I'm pretty sure that's not correct. I saw flawless achievements for Thuuga and Pawbuster for some of my guildmates on guild events recently. So there should be separate ones for each named.
I'm coming for the achievements too and what's more, I'd be willing to sponsor all raid repairs if we were willing to wipe and try named again in order to get em em flawless (not try all night, but couple of extra tries if people screwed up, no one should be dying to this crap anyway.)
Or I can just offer up a reward to be /randomed for if the boss is dropped without deaths. Just to add extra fun
