All stats scaling is pretty meh. Both crit and SS are kinda meh. It takes too many stat points to increase any secondary significantly.
The difference in dps between any food (HQ or not, "best" stats or not) is going to be on the order of like 1-10 dps. Completely not relevant. Go with what is cheaper =D
SS does not affect festers/deathflare, but is still much better than before.
I haven't had the issue of needing more accuracy. Unless all the gordian gear has absolutely none on it, I'm pretty sure (esp since we have ZERO choice in gear atm) there is no point in accuracy foods. If it turns out savage has extreme acc requirements then we will eat acc food, but for now, we are way overcap in just law gear.
