Not sure if it's possible to directly interfere with skills instead of just changing the parameters for skills. Namin? believes that the GM has said how these type of suggestions need to go to eA and not something heRO GM team will manage =o
(a lot of people still use steel tempering actually... Namin? knows quite a few. The need for steel is just not satisfied from pure mining, but also using the iron/coal from mining to make them into more steel as well. True that she does not know of people using iron and enchanted stone ore though... but not like any Priests use slow poison and that skill floats around in RO anyway. Guess it is another mystery of Gravity programmers.)
