I know 'community service' isn't so high on everyone's list and there is no obligation to do so, but maybe consider assisting other players with content?

Helping others with Vagary for Empyrean unlocks, Ambuscade, HTBF, Omen, etc. will help that population catch-up and encourage creation of new content, keep subscriptions up, create a larger pool of players you can group up with in the future. Yes, it is hard when you help people and they leave later on, but there are those few that stick around!
