I am disappointed that
a) they are repeating the bonus event so shortly after it had finished, and
b) it is the World Boss Rush instead of the Meta-Event Rush, which was a lot more fun IMO.
Both are pseudo-content, as they are merely adding rewards to already existing content, but that's not the point. While I am glad that we finally have PvE bonus weeks after all these years, I wish there was more variety to them. (For instance, I wouldn't mind another double-XP bonus week with special rewards for map completion, if they can't come up with something different altogether.)
