I have noticed that the base damage difference between one-handed mace/sword/axe is not too dissimilar from daggers (at this point, 26 base damage for daggers and 32 base damage for the rest). Why should I not use dagger for one-handed melee characters? It may have lower damage (80% of strenght-based 1h), but it can always crit, benefit fully from warfare, and can also use dagger-exclusive rogue skills.
