It is not a net discount. The instances that are "even" with the current prices on the duty finder compared to amount of myth we used to get is Copperbellmines (Hard) and higher. Which means there are 16 instances where sold was lowered not to the half point mark of mythology. So as long as you only do Copperbell mines or harder you would have an EVEN amount of time for getting books/atma. the 16 other instances will be SLOWER than the old way. Argue whatever way you want. It's slower, or you're restriced to half the game.
