The problem with matchmaking? Not everyone is guaranteed to have a method of communication (absolutely necessary.) The Raid content is much more difficult and takes longer a standard strike or mission and without proper communication, it's too hard to organize 6 random players. The only way we can have matchmaking is if we make raids stupidly simple and easy with bullet sponge bosses that stand there and shoot at you while you take cover and fire back. It's dull and isn't challenging. No splitting up forces to defend multiple points (confluxes), no killing key targets that will kill off your team in a set time frame (oracles) no killing one key target for a relic that lets you damage the boss (Blade of Crota.) That stuff just doesn't work for groups of players with no raid experience and form of communication. There is nothing wrong with players taking the initiative to go to an external website for grouping. Matchmaking isn't an easy solution and only causes more frustration and aggression throughout the community.
