As I clear all Vanilla raids with the pets, and mounts, every week I get about 700g from the drops. Now that you can get the pets, you sell them for 2-4k. The least I have gotten in a week is 2 and the most I have gotten was 6 so you could have a lot of gold.
Now if only I could sell mounts like I could pets, it would give me another reason to go back to Malygos.
