I have to invest exactly the same number of points into WM and Agi, but now I have 22 less WPF, so that I only JUST meet the requirement for 11 PT at level 34. It's meant nothing but a nerf to anybody following a pure throwing build and there was no corresponding buff to offset it. Before I had a small surplus of WPF over what was required, so if I understand correctly my accuracy got a miniscule boost; now that I only meet the requirement I lose even that. I play naked but now I don't even have the option of wearing any significant armor, so (assuming armor weight still reduces wpf) about half of the gear I've bought is impossible to use with my build.
When the very first round of nerfing hit throw some time back, I thought it would help focus throwers on picking off wounded enemies or at least helping teammates. Ever since then though throwing has been nerfed away from viability as an independent class with the intention that it function almost completely as an alternative choice to xbows for hybrid meleers. Literally no changes except those that objectively force throwing in that direction, except for addition of throwing hammers which are useless. Throwing has never received half as much attention in terms of tweaks as any other group of weapons...and unfortunately that's probably the only reason throwing weapons remain at all viable.
PT 11 and high-tier weapon headshots kill 4/5ths of the time. Archers in leather run away from me with a throwing lance lodged in the back of their neck. It's stupid.
The easiest fix at this point would be to increase the bonus for having a PT above that required for any given throwing weapon.
