I have been lurking about results from places like DS7 and such to get the otter and kamacite farming. Kind of unsure what build(s) I should upgrade to to farm otter/kamacite/wax, well when wanting to focus on one. All four are 50, but one set sits with full shark, two with full Unkiu. The only good one is a CCWC with 130 surv, 95 retrieval, 80 speed, 70 range, 115 favor. I have mats to make 4 Syldra parts, and was planning on CCSyC (150/65/80/90/140) but felt 65 retrieval would make for poor kamacite farming (but good for say, otter). Is there a well-rounded build I could go for? Could just upgrade 2 submarines with 2 Syldra parts instead of all four with one I guess. Know it's hard to say for certainty since a lot is just theorycrafting still.
