The following affixes now have a chance to appear twice when crafting items:
All Elemental damage types
It looks like elemental dmg can only be on weapons and offhands and min/max dmg on weapons, rings and amulets. The only of them craftable are weapons and offhands. Now since my favorite class in every game is wizzard I go for wand with + ele dmg + ele dmg + min dmg + min dmg + max dmg + max dmg. At least before someone does some elegant math to prove me wrong
