With this fight in particular I'm sure there are people who didn't get to do it that would be curious to see what all the fuss was about. It could have been something in the game that would remain a challenge that people could come back to with a little help from stronger gear.
Because if Gordias proved out anything, it's that most of the playerbase doesn't like not being able to outgear things and A3S as designed was never going to fold to gear the way 4 will (and I think Midas as a whole is going to be a lot more gear-influenced, though I've yet to see most of it.) 3 was largely about everyone doing a dance, fail the dance and fail the fight, and long-term failure isn't hugely popular with most people. I like getting my teeth kicked in in a fair fight, but it's not for everyone and not making people feel bad is one of the biggest design touchstones one the game.
It does lead to a situation where the game is severely lacking in things that ask players to step up and challenge themselves, which is too bad. I'm glad I did A3S when I did. It made me better at the game and killing it was insanely satisfying (4 wasn't near As satisfying; beating 3 was the pinnacle of Gordias to me.) I'm bummed people going forward will never have the option of experiencing it. I get why they did it, but it's probably not great for the playerbase that they continue to try to marry hard content to lockouts and make everything else snoozeworthy. The game lacks in things that challenge players to try without also essentially requiring statics, which hampers new player progression.
