Well my guess is they want a community event not something only a handful of people get, imagine all the PO'ed people that participate and got nothing. People have been grinding for months now for various things, also guessing they do it a a treat to get something fairly easily and not another mind numbing grind. Just a way for them to say thanks and have some fun, not grinding content. Thats just my take on the event thing. The last event was pretty fun, atleast on our server was like a spring break beach party. Everyone got together and had some laughs, an escape from a grind for many.
