Two small wibbles.
As derpy as melee thralls are, archer thralls are infinitely worse. The scripting for how thralls fight with a bow or any ranged weapon is just not good at all.
Second wibble, there are a few legendary weapons that flip the script.
Strength based bows, due to archery deliberately sucking, aren’t that exciting.
The Agility based Greatswords, on the other hand, can bring agility focused thralls to near parity with Strength based ones.
While these are harder to get in Siptah, in the Exiled Lands they are for sale at Mek’s Place.
While this one generally finds thrall combat prowess a little laughable, the melee option for Agility thralls makes them no worse than Strength thralls in several cases.
And yes, this one knows the Katana and Shortswords are melee agility weapons.
This one has also watched the NPCs generally be very confused by these weapons and use them about as well as they do Javelins.
