Make it possible to reset a PowerPack midway to "start over" and do old quests and vanquished bad guys over again. Also make it possible to un-vanquish bad guys.
S shared this idea
I’d like to redo an entire powerpack. I don’t see this option.
Actually you can reset old powerpacks. I only joined 5 months ago though so I don't know whether that option was added since you posted.
