Why is it that you want to remove an authentic experience such as boosting from the game simply because you don’t know how to combat the excess amount of gold selling that comes from those who do it?
Boosting for XP has been around, and quite popular, long before wrath of the lich king. Even if you disagree, I’m sure many of us remember watching wow hobb’s videos on boosting SM 10 years ago.
Boosters/Gold sellers will just move on to different methods to do the same thing. You can’t combat gold selling like you “want to” because massive amounts of gold are moved and traded around GDKP’s & Gambling addons already so its hard for you to track it. You practically admitted that this is why you’re making the change in the first place.
I’m all for active efforts to improve the game’s integrity and/or economy. However, removing nostalgic experiences from a game that thrives off and is quite literally marketed as a nostalgic experience is quite absurd. These types of changes are better implemented and reserved for Season of Mastery.
I think that with the addition of fresh start servers you can safely implement this type of system into those servers so that people have the option to enjoy the game one way or the other. I think that even having some non-fresh start realms with this functionality could be healthy as well, but I suppose that’s not the problem you’re trying to solve is it?
At the end of the day, this is likely just so you can sell the inevitable “boost to 70” from the wow store because questing becoming the most viable option to level characters will definitely drive the ‘zoomer’ player base into spending money instead of time.
