Aloha Tilarta,
"In my experience, the vault entrance is too limited, you can only have two guards in it at any one time.
Which is I why I assigned the dogs, to compensate for the problem."
Mr. Handy was the key for me. Fire down bellow kind!
Plan A was quickly abandon along with B,C and D. Now still holding to plan F I was able to lv up 10 @ 50lv Dweller's (Dwells).
Yes the vault entrance is limited but not undefendable. Some of the 10 dwells have high SpEPcIAL stats and have been holding the door with zero fatalities. I've been taping Mr. Handy for the Bar-B-Q that is to die for!
My entry floor plan thus far: Door (no dwells), Elevator, 4 dwells Nuclear Reactor, 6 dwells Nuka Cola, Mr. Handy working the fire down bellow.
I had enough time to direct Mr. Handy to aid and abide the dwells above or I would let Mr. Handy walkabout the Entry RMs when I was tasking the lower levels, which are every bit equally important in the vault defenses IMOP. Just for [censored] and giggles if time allowed I would task some of the lower level dwells to the Door along with Mr. Handy to rally a universal room rush. Cha-Ching!
Note to: Todd Howard, If there were pet classes maybe I buy one or two but for now Mr. Handy hands down!
F that plan!
