Shinryu EX on content slapped pretty hard I recall, so much so that people were ranking it as 'in between O2S and O3S' in terms of DPS check leniency/tightness, PFs were not having a good time with the mechanics there. If anything, it feels like EXs have, overall, moved down the scale to be more comparable to, at most, 'first savage fight', whereas before they were a crapshoot of being anywhere from 'barely qualifies as a normal raid fight' like Lakshmi (god what a disaster that fight is) to 'between 2 and 3 Savage, leaning towards 3' like aforementioned Shin, or Thordan

Difficulty has moved away from 'execution' and more towards 'puzzle solve' I think. I'm supertrash at Rubi and the circle crap, I cannot visualize it at all. But I had no issues with Barb because it's not a 'puzzle', it's more straightforward dodging orange AOEs and constantly getting blasted by Knuckle Drum. I think they need to go more towards Barb design, and stop doing puzzle mechanics so much that can be dorito'd. Rubi is super hard for me as previously mentioned, but as long as one of the other 7 players in the team knows how it works, then all 8 of us get through the fight fine. That's weird design choice to me, because it means I cleared the fight without 'understanding' it
