First, I would like to point out that there are many ways to obtain both companion tokens and the option for using AD if it is more feasible, which it currently is. Note that companion tokens should be sold by players for a value of below 10k per unit, as they have a competitor that is the game, as this provides the opportunity to upgrade the companion via AD at the previously mentioned price, and this is from the legendary version to mythical the most expensive of the game. Even so these tokens are sold above that. Of course it is a right of the seller to determine the price, and many who do not make basic calculations fall into this trap.
But as the title says, there is a problem in the mount tokens, since this for those who are f2p can only be acquired via AH (I know that they also fall into the baus of dungeons and in some events), and there is no option via AD that would serve as a parameter for these as there is for companion tokens. In my view the same system for companions should be implemented for mounts, even if the seller does the same as what it does with fellow tokens, we would still have a cheaper option since there is clearly inflation in the game due to the amount of AD of bondings and high demand for specific items for character improvement.
Only one option other than AH.
