Where are Zealot Greathammers?

At first i though i am just unlucky and those doesn't drop or appear on vendors. But then i looked on trade - absolutely none.

So i am level 60, still using level-30 unique greathammer with splash damage. And you tell me next upgrade for me will be only on level-78 with Fanatic Greathammer?
Where did level-50 Zealot Greathammers go?

Those are still available on trade search, just zero results. And yes, i've reset search to ensure it will look for ANY Zealot Greathammer.

They are still available in standard, but not in Rise of the Abyssal
