I feel like you guys are missing the point of this world event. The point is to see a world in ruins ready to be destroyed. There is supposed to be chaos. It is for this reason alone that they did the final save before it started (It wouldn't be fair to kill everybody repeatedly and repeatedly deteriorate everybody's gear).
Fact: Everything you do right now will not be saved. SE is not expecting anybody to do anything right now. They aren't not going to show you some important piece of the story because we all didn't figure out how to mass pray at multiple stones. Everybody is going to see the full story (if any) if they tune in at the impact time. Everything that is happening right now is for fun. There is no goal or objective. Just enjoy it.
The only reason there are articles about the praying on the front page is because that's the final step of the storyline. You take out Darnus and then you are asked to pray at the deity stones (Quest: "Living on a Prayer"). The articles are for people who didn't complete the story...they are essentially informing those players that people around the world are praying to their deities. Then when impact time hits and the deities appear and whisk us all away to a timeless realm it will make sense to those who weren't able to complete the storyline.
The praying articles are nothing but a way to catch others up to speed who did not finish the 7th umbral storyline. That is the more logical answer.
