Until they fix the fact that you have to go to external websites to matchmake most every bit of end-game content, it's not fixed.
Stop making excuses for their laziness. There are a ton of viable options to offer ways for people in-game to meet and plan a raid. Forcing them to do it on GAF, Reddit, Gamefaqs etc is idiocy at its finest. Defending that idiocy is horrible.
If you played the game actually you would know that matchmaking in raids would be HORRIBLE. In fact, matchmaking barely works for the Weekly Heroic.
