They would nerf the difficulty of raids if they added matchmaking. When people would try the matchmaking and realized that they fail 99% of the time, they would whine on the forums until the difficulty was reduced. It’s happened before with reckoning.

If people struggled with reckoning matchmaking, how well would they do in a raid?
