Thank you, that's the bit I needed to know
Axe is single Assault(++) and the gun is single Pride(++).
So if I read the bit about skill levels correctly on the wiki, SLvl20 SR Assault(+) = Slvl14 SSR Assault(++) in both percentage wise(13%) and the number of required fodder(210 R weapons). So after spending same amount of resources Level 85 SR weapon should have slightly better stats but level 50 SSR has more room for growth. Is that correct?
