IMO, Bioware did a great job with this event. It is always fun when you can create large groups and do something together. Like farming the world bosses during the Gree and Rakghoul event, doing mass pvp, porting the whole server to the Rishi datacrons or the Yavin world boss. This event was no exception, and it is the reason why SWTOR has a much better community than other MMOs in my opinion.
