Did something happen to the playerbase? Nobody knows what to do anymore

I haven't played for a year or two, so just came back to do some farming etc

Somehow nobody seems to know what objectives are anymore in pubs. Void cascades fissures fail regularly because people don't seem to know that you need to go and defend multiple exolizers. I've been doing some Follie's hunt and people just run around killing things without bothering to do any of the actual painting. What's going on
