I can understand this argument, because if we think about it, reforging was never meant to be what it became. The initial purpose of reforging back when it was first announced was to allow players who got a drop that was otherwise significantly better than what they had, but itemized for a different role (so, as an example, a cloth piece itemized for healing over DPS) to make that drop better for the role they intended to use it for. So if your tankadin got a pair of plate lets with crit and expertise on them, he or she could swap some of the crit to a stat more useful for tanking. However, players being what they are, they immediately grasped that reforging also allowed them to trade away stats that were less effective on gear for stats that were more effective. Reforging allowed players to customize their hit and expertise in ways that had never been accessible before, allowed for dump stats to be dumped with even more efficiency than before - it was the absolute biggest change to the game in years, and ended up the largest single legacy of Cataclysm.
Mushan's arguments about removing the process of reforging are good, and I'm not going to belabor them here - instead, what I'm going to do is discuss my own personal feelings on reforging, and how it benefits the game.
