I tried waiting to start it at midnight but oddly more people where outside then.
I have nothing that can easily kill them, even my legendary gear is ineffective. besides with the way it loads things out of sight and how insanely weak and stupid npcs are many will die before I get there.
Wish they made them in waves and kept npcs that where not fit to fight (town drunks and bards) cowering indoors.
If theres nothing I can do, I think thats it for me and skyrim, sick of playing a game that fights itself at every turn.
