I agree with you but of all the MMOS i have played, such events are tied into the actual world game content like special events, missions etc as an alternative to acquire some items.
I read all the patch notes and i found no such thing. I was hoping for some open world events or missions related to this event.
Life Day is a Wookiee tradition and a sort of equivalent to Christmas. Once Kashyyyk is made explorable in the game, then can the developers properly expand the event to play similar to the Grand Acquisitions Race or the Rakghoul event. All we can do is hope that the devs are already planning on making Kashyyyk available in the near-future.
