no, because crafting already give you better chance by default.

example like i looking for my dream monk fist. all at AH freaking damn expensive.

i bought a fist plan with 5 prop from AH, just keep crafting until you get your dream weapon
it's faster to get than farming because you are aiming on one thing. Its keep rolling the dice for the Fist.
i still havent get my dream fist yet.

I thought you need to craft 20 in a row to get better rolls?
