There is still need for better gear because not every patch dungeon syncs down to the same level. Anabeseios has a higher min ilvl than Asphodelos. Aglaia has a lower ilvl than Thaleia. The first MSQ patch dungeon has a lower ilvl than the last. Gearing played an important part for me and my friend because we had to keep up with the minimum item level.
I like the idea of a proper sync very much and heard this wish for years from so many people. And it did wonders for the final 6.0 trial where you only couldn't skip the "second enrage" because it was mandatory before they added proper sync. The fights were supposed to be doable for casuals at patch day and as someone who is semi-casual to midcore and played all EW duties on their respective patch day, I feel qualified to say this is a vastly different and way more fun experience. Yes, the scales in particular invited some people to troll, but idk, most of the time I ran them, people were solving the mechanic just fine, and it was nice you could use a ranged or caster LB2 on the clones.

It is also still simply a bit more interesting and unusual than your average "burn down enemy until ded, maybe dodge an AOE" thing. And not every patch duty is Aglaia... By now there are times where you don't even make it to LB2 in the first panda normal raid, or in Troia, that's just sad. You are missing out on so many interesting things. :/
