All the people claiming ourage and whatever else might pop up should be taken with a grain of salt. So many said they would quit if the game had f2p features and got a cashshop and so on and that SE is much better and that is why they prefer XIV etc. In the end those same people started justifying those very things saying they are good as soon as they were implemented. Like you OP I doubt it will happen but if it does I am sure there would be many willing to pay. Even many claiming its a horrible idea now because as soon as it is in the game its a good idea that will be defended tooth and nail.
