So I made an STF pure thrower: 27/12 with 4WM and 9PT all wpf into throwing.
The accuracy is decent.
BUT, in the first hour of playing I noticed people tend to survive way too many heavy throwing axes. On multiple occasions, I hit someone wearing a heraldic mail with tabard 3 times (most in the chest, sometimes 1 in the leg) and they would just walk away with my throwing axes.
A strength build in a byrnie took 3 and walked away too.
Yes, they were all coming at me, cuz I got cleaved when I was standing around wondering why they were still alive.
Horses on the other hand all died in 1 hit.
Seems like I need to bring jarids at least to bring infantry down. HTA's are for killing archers and horses.
That's about right, though with horses it depends on how/where you hit them. Headshot on a charging horse with a heavy throwing axe will kill them. If you miss the head and hit the body (or worse, leg) it won't (and you'll probably get lanced). Hitting the rider might kill him unless he has heavy armor (or you hit him in the arm/leg) although that will still interrupt his intended lancing.
If the horse is running away from you, you can throw at it all day without killing it.
Basically throwing vs horses is my favorite thing but if you screw up then the cav will one-shot you. Beats trying to fend off cavalry with a sword, though.
Versus infantry you should just count on using throwing to soften them up a bit. Otherwise you'd better plan on playing like Chucky -- throw axes, run away, pick up axes, throw axes, run away some more... you won't kill most people before they can close with you so you'd better run (and hope they don't have their own throwing daggers to stun you with...) or else have a build that can follow up with good melee.
Ditto for fighting cav, incidentally. You may have killed the horse in one headshot but an armored rider will take a shot or two and still close the gap to kill you if you can't melee him or flat out run away. And then there's shielders...
Figthing plate guys with throwing is kind of silly too. Even if you win, he'll end up on the ground with the majority of your ammunition stuck in his armor.
This is why I encourage throwing hybrids but not pure throwers.
