Even states he would like to know so there is an off chance it doesn't make it into for 4.25 and that is just for susie and lakshi mounts.

And if you take a look at the HW patches, you'll see that SE has never added the mount from an EX trial until a few patches after it's been introduced. If 4.25 adds the Susano/Lakshmi mounts to the vendor, they likely won't be adding the Shinryu/Byakko mounts to it until 4.35/4.45.

As for ways to reduce the amount of RNG on drops, the totems were exactly their way of a safety net. You'll be able to buy a weapon every 10 runs. This wasn't the case in ARR, where you had to farm a primal until it dropped the right weapon.
