You don't have to beat the raid bosses to finish the story line, just go back to quests and continue through the quest as usual. The story however only goes to the end of chapter 10. After that the storyline has "ended" (without any true completion, ever) and the quests go in a loop for those looking for more raid bosses. The event ends when the time expires, in this case on August 28, at 11:59pm PST.
