As an ally, I don't always know what my hero has completed by the name of the activity on the activity wall - so I can see what he's doing and comment or like. When I go to click on the activity it just takes me to the activity page. If I want to find out what "birds of a feather" is, for instance, I have to look through the quests, powerups, etc. to try to find out. It would be simpler if clicking on the activity took me to a description of that activity.
