The problem with waiting is that it will make my mount cost significantly more expensive...

Right now by doing the quest I only have to pay the 250g for the "re-use" mats once, the other 3 times I only have to pay 150-200g for the other mats. So I'm getting 4 mounts for something like 1000g, if I wait till the patch I now have to pay somethingl ike 2800g for the same mounts
