This. Spend those same 3 FGs on stamina refills + running 12-3/12-5/13 + SGs and you're likely to get at least 1 ampy AND several level 100 manyus. The "deal" is garbage (terrible investment unless you just CAN'T POSSIBLY spend the time to run those missions repeatedly with the same FGs used on stamina). I suppose it's also viable for new players who are willing to spend for an early boost, but that's still sketchy...
