I think I see where the OP is coming from. I also like to pug and help players who are struggling. That's hard to do when fights require every party member to be good. That's an unreasonable expectation for pugs.

2.1 brought some new DF content that is too hard for pugs. EMs are miserable for pugs, and Ultima HM is also too hard. That level of difficulty should be reserved for FCs and should not be on DF.

2.1 also brought CT, which is puggable, and Mog and Pharos, which are borderline but a bit too hard. Copperbell and Haukke are close to ok. DR added good pug opportunities. PF is great for finding players with similar goals but doesn't help with content that is too difficult for the average player.

So ... 2.1 added puggable content. It also added some fights to DF that are too difficult. Those fights should either be removed from DF or tuned so that they're fun for pugs. Pugs max out on what they can do, and 2.1 overshot on DF difficulty.
