Aww, it's been nerfed to the ground now, even at synched ilvl, they've nerfed actual mechanics.
It absolutely did unleash hell. People had complained Final Coil was too easy so the developers said, ok, TRY THIS THEN. There were a few oversights. Firstly, the new expansion meant people had to relearn their jobs. New jobs needed to be balanced and for a long time there was an actual players vs developers argument about Machinist in particular. The players stated the job was weak, SE stated that it wasn't weak, we were just bad. Adjustments were made later of course. Astrologian suffered the same sort of treatment.
While job rotations got far more complex than they were from ARR, the actual DPS requirement of Gordias basically meant if you didn't have a WHM that could carry the group while your tanks stayed in dps stance and your scholar was full time dps - you didn't clear. Tanks were also putting points into strength for the extra DPS which made them squishy, which made the healing check even harder. The world first players complained the dps check was so high it was actually a gear gate.
Not only all this - the fights were super dull. A3s was the most interesting but the others were just a chore. You had to preform at 100% capacity with zero mistakes through boring mechs. (My opinion). Not only was Gordias a BIG step up, pug groups couldn't even clear Bismark. The first primal had a high dps check too. The skill gap between people who challenged savage and casual players became massive. Groups fell over, people quit. The one part that really stands out remembering Gordias was how many hours I had to sink into crafting pots and food. One per craft, one minute + per craft, I needed 33 pots per our raid time, plus I crafted for others. I had to set aside hours per week each raid to struggle street these crafts we NEEDED to push our dps. Heavensward was a lot more of a grind to start off with.
Gordias made my group better players. Like I said, it was hard, it broke us weekly but it was such an achievement to get through it.
Now, we're finding "savage" in stormblood pretty tame. Week one / two clears. I understood they were pretty scared of making the same mistakes as Gordias but I thought they would turn it up a little for Sigma :/ In fact I'm sure they said the raids would scale up in difficulty so it's a little disappointing that they haven't.
I'm glad they're doing the Ultimate's. At least that's something to prog on while Savage has become the weeklies.
