Typical farming days - DW eating poligons

Will it be worth it to save for GT+ already at this point?

I have calculated that I would need to save 5900 stones to unlock last 2 UW (SM and PS) and unlock GT+

Should I push max cd for DW and GT first (currently at 110 seconds both and would need 1384 stones)?

With the total of around 6.8k stones, I feel like i can progress with legends if I put more also to my BH duration and CF slow or even progressing my CL, but I am hoping to improve my econ also.
