Check, thnx! Was already aware of the max endurance + lvling, am currently maxing E on all my lvl 1 dwellers (and after that the stat in the room they will be assigned to plus L). When I reach the 60 pop limit (no deathclaws for me yet ) I will start discarding (aka kick'em into the wastes till they die from it ) my first group of dwellers I currently need to keep the shelter running.

Great advice. Unfortunately, I'm reading this after maxing everything. Great game.

I wish it did. My first real room of death is a P room with everyone at 10. Doesn't seem to stop things faster. GUNS...work.
