Let's play cynic for a second: "Adding mini-games would be to much work for SE to do."

SE has already stated they are working on ffvii gold saucer-like area for FFXIV:AR, so it is assumed adding mini-games is already in the works, why not use a few to combat botting?

"SE has more important thing to work on besides this"

The game's economy is the lifeblood of the game, botters flooding the AH are in the early stages of ruining the economy. Addressing the problem before it gets outta hand is pretty dang important.
