u still not getting it
weapon preference 20% bonus apply only to individual weapon.
weaponskill apply to entire grid.
they are completely different calculation, that is why weaponskill apply 10x, and weapon preference do not multiply to 200% bonus.
u can easily prove or disprove this. in fact, Greggers and myself proved weaponskill apply to entire grid on page 3 of FAQ/Q&A thread.
additionally, we keep pinging u on discord so it can be discussed faster but u ignoring.
