Assuming you don't have it yet, you can still work on getting the badge for bumping into the shield. That's a hard one to get.

Reasons I'm not a dev:   I'd make bumping into the shield count toward the badges that you get from the MSR.  (exploration, Master of Arms, the bomb one...)

But it would be a random choice that had a long time out...
