Mark of the Heavy Hide - Rank 3 - Bugged or WAI?

[Piene]

Hey everyone,

I recently picked up enchanting on my Tank-Alt, and checked where to get all the rank 2/3 stuff. As a Tank, naturally I was mostly interested in the Mark of the Heavy Hide enchant, and already dreaded the requirements for obtaining rank 2 of it -> A random drop from bears (a quite rare one also) AND the rep-requirement: Dreamweavers exalted (taken from wowhead) which sounded pretty annoying.

Now today, I did LFR and the Rank 3 Recipe dropped from Ursoc, now I was wondering why the "Requires previous Rank" tooltip was missing, but it turned out that I could just learn the rank 3 recipe, without even having the rank 2 one.
Is this working as intended? Does it work like that on any other recipes as well?

Rank 3 of the Mark of the Trained Soldier can also be learned without rank 2, or at least it was possible when I did it.
