But the Binding Coil of Bahamut sits still untouched. The raids added in the expansions (Alexander, Omega, etc.) solved this by making a normal difficulty level version of them as well as a hard ('Savage') version of them so that you could actually play them through matchmaking. but because they are still considered difficult they are not a part of any roulette, so there is basically no way to get a full party with the Duty Finder at all. They later added them to the Duty Finder (FFXIV's matchmaking system).
Because they were not intended for randoms being matched up together they were not in the Duty Finders and required pre-made parties. The Binding Coil of Bahamut were the original series of raids added to FFXIV and were basically hard mode content for high level players. And by fix I mean actually make it available to the average player through the Duty Finder.
