imo you shouldn't craft gloves for a javazon. Rare gloves with +2 jav, 10-20ias, and some leech or added str and or dex aren't that hard to drop. Pick up all the rare gloves you find in nm and hell. I've gotten many pairs of similar gloves before. I think crafting gloves would be better for a bowazon, especially hit power (potential for 20ias, knockback, +2 bow/passive and leech.)
Just recently i crafted +2 jav, 20 ias, and life/dex and some resist gloves, as well as CB. Hitpower will give you "decent" gloves more often. In 09, I crafted several hundred of both.
With hitpower, good mods might have been:
leach OR res, never seemed to get both
10 Crushing Blow
+dex and or life.
For javas however, you dont need kb, thus making it more apt to go with the ones that turn out godly more often. Just a note on their values, a pair of gloves like the aforementioned gave me about 20 sojs when it took 2 sojs to buy a shaft.
