i stopped crafting the 5 prop gloves a week ago. it costs about 66k per glove, and i usually even out. but trying to nickel and dime the gloves to break even was a bit too much work, especially when you only have 10 AH slots to use. i did craft a few 5mil+ gloves and ended up making 15mil or so, but its a bit like hitting the lottery... not for the faint of heart. i probably crafted 200 gloves, only selling about 10 of them on the AH. the rest were vendor fodder, or are still in my stash collecting dust.
if you're crafting anything, this is what sells:
(1) high property = 1k (vendor)
(2) high property = 10-50k
(3) high property = 100-200k
(4) high property = 1mil-5mil
(5) high property = 5mil-15mil
(6) high property = 15mil-infinity
if you can afford it, or already have a 6 property armor plan... then your chances of breaking even are higher. but the principle costs will be higher as well. so again, not for the faint of heart. you're essentially gambling.
