Alchemy-very broken/exploitable

many recipes not working, some requiring only a couple of the listed ingredients to actually make. failure rate and ingredient loss from failures is too low. cast/creation time is too fast and doesn't seem to change as you level up. stat buff, healing, and special potion results selling back to the merchants for more than 100% of the cost of the materials required to make.(starting with ~169gp I went from Alchemy level 1 to 734 in about 1.5 hours ending with 1,573gp)
