Well one of us is certainly wrong, but it's not me.
You can't tell me that after all this time, after nearly a decade of leveling content being faceroll, that they're going to nerf it for the small (five) amount of people that actually enjoy leveling. They're doing it to sell more boosts. $$$$$$$$$$$$.
Leveling serves as nothing but an obstacle to get to the actual game, so making it take longer is just a way to sell more boosts. Pretty simple really. If you want to torture yourself for heritage armor level, otherwise most normal people will probably just buy a boost instead of wasting countless hours of their time to get to the actual game.
