Honestly, I still stand by my opinion of, if you enter a duty finder, expect peeps to not know the fight....... I would much rather people learn the fight in DF or a PF made specifically for learning. I only get annoyed at players who don't know a fight who join a farm party or a clear party that states "must know most of the fight."
Also on the note of "look it up." This too, is what I feel DF is for. Not every player wants to learn from a guide and not every player is going to be present at the launch of new patches. I personally like to try a few DF runs before looking at a guide as well. I will note though, that I state I am new ahead of time in case the group wants to vote kick me. XD (I will sympathize with those up late who want to run the Alex floors that it can get annoying being put in a group with new players though)
Ultimately, though, the patch just came out and isn't even a week old and I too, have seen some salt. That being said, I have been in a few midas parties who were willing to stick it out almost to the last 10 minutes.
I will say, though, I still feel that over all the ff14 community is much more tolerant than many other mmos, with this subject.
