Gordias was exactly how it should be. Playerbase is more informed, we have crossworld parties and connections are better. Tankbusters and basic dumb raid aoes don't need castbars, A2 style fight needs to happen again and fights generally need far more adds, slows and stuns need to matter, and you shouldn't be removing sizeable chunk of the fight mechanics from the end by just dpsing more with gear over time.
E1S is the only one where we see all the mechanics happen at least once by now, and that's just because it loops the post-cutscene phase twice. Skipping the boring heal spam checks is plenty fine, but you don't even see the hardest mechanic phase of E2 and E3 if you didn't mass suicide and heal LB.
