Maybe so, but I prefer pure strength/vitality combination, as do many others. I like to equip my thralls with maces and pit them against world bosses. Daggers and agility work well enough for some bosses, but others? Not so much. I’d much rather have a str/vit thrall on my side when facing off against the undead and other enemies that aren’t subject to debuffs like bleed and poison, such as Rockslide or most of the Unnamed City bosses.
