I have been killing time waiting for the next update so I have been making my dwellers buff themselves while I wait. Out of 200 dwellers I have:
28 Maxed working in Nuclear reactors
14 maxed working in Nuka Cola plants
2 maxed working in the Radio Room
8 not maxed working in Nuka Cola and Radio (waiting for some more maxes to shift them into buffing mode)
148 in buffing mode
I have purged all weapons with less than 6 damage now and hope to start Wasteland runs again after I max out the last two production rooms
Anyone else killing time by creating the perfect Uber Dwellers 

but of course not all. Total 174 dwellers. In few days ~5 dwellers will be maxed with all stats and i will send them to wasteland. Oh and by the way, I'm not cheating with time to make it faster
