As you build your weapon grid with assault SSRs/SRs of your primary element (with maybe secondary/dual element at the same time..), what's generally the better way to approach skill level ups? Should they go to SSRs first? SRs first? Even spread? I've read a lot of the posts around the forum about what to prioritize but I'm just not sure how to distribute my Rs for skill levels (and later SRs/Grails). Thank you.
