Just wondering if daggers are bugged to not receive bonus from Fortify One Handed or are they working as intended. Granted daggers get x15/x30 for sneak attacks BUT some may want to go heavy armor and daggers for straight melee (not me but just saying ;p) or offhanding a dagger sometimes.
Likely "working as intended". It's possible to get 90x backstab damage between Assassin's Blade, Dual Savagery, Shrouded Gloves, and Berserker Rage.
Daggers are for back-stabbing, not for toe-to-toe combat.
