The City of Heroes forum has a new announcement from Tim “Black Scorpion” Sweeney about an update coming to Issue 19 called the Strike Pack. From the post: "The Strike Pack introduces the Weekly Strike Target and the Rare and Very Rare tiers of the Incarnate Alpha Slot."
Weekly Strike Target: Every week, we will announce one Task Force and one Strike Force (or instead one Co-Op Task Force) that will give increased rewards for that week. The first time a character completes the Weekly Strike Target in the week, they receive double merits and a bunch of additional XP. Even if you “go rogue” and do the other side’s Weekly Strike Target as well, you’ll only get that reward for your first in a given week. After running it once, your character can earn progress toward some brand new badges for helping others by running it as many times as you like. Of course, you can run the WST on as many characters as you have the inclination for and get the increased rewards on each. The Weekly Strike Target will change every Tuesday morning.
