After the patch this week, now we basically have unlimited supply of community head gear (3 hr cooldown for camp quest and you get to choose what you want + can put in a huge party of alts per run). So with the current safe certs prices, will it be better to just refine them normally and blow them up if failed?
If going the blown up route, probability-wise, how many HG will need to be stocked to make one +9?
