My math is coming up with different, but still ugly numbers. 19 augs needed at 500 a pop is 9500 coins. You're still going to use Forgotten gemstone/ Nathsar Diamond. The one stat you want for the TS and dropped Aug from TOV at minimum. Some classes might decide they could use a few more different stats this year I bet. 23 coins per mission, so that's 413 successful missions to buy at most 19 augs with coins. Still awful.
