I've had Mendro one-shot me a couple of times on my old 24/21 pikeman build. Don't know how much throwing's been changed a since then though. I haven't tried throwing lances since they were changed myself, but before that, they were easily op on low-populated servers, and up on high-populated ones. If ammo levels could be changed depending on server size...
When I played a bit yesterday evening, there were throwers everywhere. Axes, lances and spears flying everywhere. A bunch of throwers are arguably more annoying than a bunch of horse ranged.
