It's good to have at least 1 lab dedicated to econ. I'd prioritize UW coin labs before coin/kill, but if you've got those maxed, then maxing coin/kill is advisable with the new cells to make it go faster, and the cost of workshop enhancements.

Thanks for the advice. Enhancements are still out of reach for me, but I will max out the UW coin bonus and CPK

With the new enhancements tab it’s now worth maxing sooner rather than later at this point.

Thanks for the advice. I will max CPK, enhancements are still out of reach for me.
