Not Enough Currency - Campaign

Played since early access last Dec, all releases. Sorc always. This league seems even worse for both gear and currency. Found a good +2 skiller staff early. Made it through Acts 1-2 easy. Act 3 ramped up hard and now Act 4 is causing me to question continuing. No significant drops since. Ran rarity early, ~30% but had to change over for ES and res. OK, so now I need to roll some rarity and res'es...I have plenty of trans/augs. I have found ~12 x's. How are we to progress when I cannot craft?
