As you admitted, you aren't that great of a player. Matchmaking would be geared towards players like you. While you would be able to get in a group with match making, you probably wouldn't be able to complete the raid. This would lead to an outcry of how Atheon needs to be nerfed and oracles have too much health etc etc. This is the sole reason I object to Matchmaking. For any former WoW players, most would agree that [b]Raid Finder[/b](a Matchmaking system for the raids) destroyed the endgame and WoW has been bleeding subscribers ever since.
