If Fresh Classic or SoM 2 had just 1 change - the anti-boost feature. I think the game would be at a solid state. To me it feels unfair for a player to be able to get to level 60 in a day or two from paying a lv60 Mage to boost them.
I think Blizzard agreed this was not how the game was intended, hence boosting was removed towards the end of TBC Classic. I think it will make it an incentive for people to play the game and interact with folks in the open world.
