You'll just be approaching those grades with a new mechanic or Second hand tool now.
Short and sweet version: Second hand tool mechanic may be changing but the achievements are -NOT- The achievements only focus on the Grade locations. They aren't going to punish players who have been using their second hand tool. If you miss out on these spear fishing achievements now, don't sweat it. They'll be in ARR, just that now you will be finishing off the rest of the old achievement under a new name and mini game.
