Thori'dal, the Stars' Fury

This achievement is in the 'Feats of Strength' section. You do not recieve Achievement points for any FoS Achievements.

Post Patch 3.2, it's been confirmed by the Blue that for those who can not equip the Legendary items, we can not get the associated Feats of Strength Achievements. Per Blue Dev, the change was made "due to the new instance item trading feature" implemented in Patch 3.2.

I can confirm this, as I acquired Thori'dal, the Stars' Fury for my Death Knight a day after the implementation of Patch 3.2, but I did not get the Feat of Strength Achievement.

Here's the link with Blue's response:

So for the aspiring players trying to get the FoS associated with BC legendaries, I say don't waste your time if you can't equip them!

This Feat of Strength will not only NOT be rewarded to non-hunters/rogues/warriors who loot the bow, but the GMs will not give you the Feat of Strength if you submit a ticket, either. I solo'd Kil'jaeden on my Death Knight earlier today and didn't expect that he'd drop the bow (which would make it twice in a row - I had brought a rogue along last time), but he did. I submitted a ticket explaining the situation. A GM contacted me ingame saying that their policy isn't to award achievements ever, and I cited the example posted by magefury5 on this page. After a long pause, the GM responded:
"Aaalright found all the notes and information regarding this. The FoS was handed out at that time because the change had been unannounced and there were a lot of special factors playing into that case. Now that we are here, where the change has been implemented and in place for years with all verbage regarding the FoS we will not be able to grant this achievement."

So if you care about the FoS at all, bring one of the classes that can wield the weapon.
