You also don't have to play the game. For a mount collector it would be a slap in the face if Legion would close the gold fountain that the WoD Garrison is, don't add something similar and put an unique mount behind a gold wall that is worth 500-1000$ in token gold. But I don't think that this is what is happening. The price is high, but 2 million gold will be like 200k gold now. Expensive but still a number a normal gamer can come up with in a few months.
