they should put in the fix to make killable-npc, especially the normal citizen to run away from dragon, not fighitng the dragon with dagger and cloth.
This is an general AI weakness in all computer games, they attack anything hostile even if no chance of winning.
Should be an check here, I'm have no weapon, armor or fighting skill, that is an bloody dragon, the guards is already fighting it, perhaps I should stay away.
At least Oblivion had an bravery variable who determined if the npc would fight or run but it did not work well,
Improved since Morrowind, still remember the stupid runaway argonian slave who attacked an faraway orgrim who ignored us, he was unarmed and naked and managed to run in my line of fire all the way up so the orgrim killed him in one hit.
