Lord of the Rings Online is that gathering professions don't line up with crafting professions. Leveling up a non-gathering skill takes more resources than you gather while leveling up the appropriate gathering skill. The newest developer diary explains how Riders of Rohan addresses this problem with new "processing" recipes that allow you to turn a resource into shavings, which can subsequently be turned back into the original item.
That's not the only change coming to crafting with the new expansion. Players can expect two full sets of armor for the crafting, one at level 80 and one at level 85. There are also new crafting instances, new crafted relics, and a new rank added on to craft guild reputations. If you like to get your hands dirty with crafting in Lord of the Rings Online, swing on over to the developer diary for the full details.
