The more you transfer, the more you lose experience. If you do it twice, you have 49% of your original experience left (0.7x0.7=0.49). This means that you should not transfer to the newest mount every time. You are better off tranfering only once, or as little as possible.
Tynon said that they didn't want defensive capabilities to get out of control, but the new mounts have more and more HP. It doesn't seem to make sense to me, but hey.
The choice of changing to another mount isn't easy. You need to pay coins, but also lose experience. If you plan on getting another mount in the future after that mount you just bought and transfered to, this means the coins you spent on buying a mount will be lost forever (bad investment). Moreover, you get less experience in the end because you do multiple transfers (bad investment).
So buying a new mount is a bad investment considering that you'll eventually change to another mount. You would be better off getting directly to the last mount you want. The problem is, which is the last mount? There will always be new ones, which makes it seem like Tynon is forcing us to make bad investments.
Right now, I have a white bear. At the moment, I'd be better off with a dragon. But I know someday I'll get the chimera, so I'm not wasting experience and coins on a dragon. But once I get the chimera, a new mount will be out, making the chimera a bad investment.
This is exactly what happened to Herby. He bought the Windrunner and found out he had made a really bad investment with what seemed to be a good investment.
Yes, there will be other mounts in the future, and we'll have to decide when we want to make bad investments. I'm not a big fan of this system. We invest in heroes, build them up, and they all remain useful for the most part. But mounts, you just get rid of them once you get to the next one. At least if you could sell them.
