Most of the talk about the update that got reversed understandably revolved around the inefficiencies with sending and receiving lives. That was a huge deal that affected many people's ability to play, so that's what we all focused on.
But there were some good things in there that I miss.
The ability to send and receive boosters. Although this was also inefficient, I liked being able to help people out with boosters. Getting them was nice too.
Getting stamps through Shipmates and 4-in-a-row also provided more incentive for people (including me) to play these games.
I hope the developers will take some time to think about how to integrate these or similar ideas in the future.
