Now that the patterns and materials for the armor quests are no drop, do they really need to drop on mobs that are like 40+? I see no reason for this, cept to make players waste their time destroying them. Just remove them from their loot tables all together.
I want to add, that although I agree with this, a lot of these items end up on my vendor for 1 or 2 plat each, unless I run out of inventory space. I know what others save them as well for newbies or twinks.
