TESTED TO BE FALSE
Get out your tinfoil hat.
So as I was on my last scribe today, about to make DMC, a thought popped up in my head...what if making DMC at each of the various temples would let you make only cards from the temple, i.e. Tiger cards if you were at the Temple of the White Tiger. Sort of like Alchemy in Cata.
I needed Serpent cards so I headed to Temple of Jade Serpent, and I had 3 Scrolls of Wisdom. I was standing directly in front of the Temple/instance.
It could have been pure chance, and it probably is, but 2 out of the 3 came out Serpents. I don't have any more Scrolls to test today, but I was thinking maybe someone here might test this more. I KNOW it was probably just a fluke, but now it's driving me crazy that I can't test this for another 14 hours.
