As you see the title of this thread, third time is the charm.
I am the third person to try to keep an active progression thread and the person before me thought that extreme primals were not worth tracking. I however thought they were a feat worth mentioning and updated any people who said they killed it. I would expect any FC who cleared through T4 to have gotten the primals as well, but I kept it to screenshots or no progress to get people ready for the new content. Also, as you can see, I am no longer updating the old content so any new FCs with old content kills do not get added to that list.
