Definitely need more special events, and folks participating in them. Something much closer to the timeframe that was typically seen in the beta. 3 an hour (or more per zone) would be a solid improvement given the bounty. I haven't seen any since starting and I managed to get into 4 or so in the short time I was in the beta while doing patrols.
