I just discovered that regardless of what it might say the Absolute Minimum Level an item is that you can only lower its actual Minimum Level requirement by 2 using 1 Masterful Craftsmanship Shard, and only 1 will have any effect. I learned this the hard way by trying to use 3 on a suit of armor I crafted, only 1 worked. So if you can only lower the ML by -2 then why tell me that my armor I just crafted is ML19 with a AML10 when all I can ever hope for is ML17. I think it is very misleading, suggesting that somehow this item can be brought down to this level and think it should be made clear that this IS NOT the ML that is actually possible. I'm sure there are good reasons for AML but the way it stands it is very confusing.
