God, can people read the whole discussion before jumping to conclusions? -.-
You don't get it. I had all the necessary cross-skills when I leveled my crafters back in ARR/HW. Crafting quests are mind-numbing and time-consuming, so I only did the ones necessary to get the cross-skills needed for decent crafting. I didn't craft much in SB, but I decided to give the restoration a shot now in ShB. But then with the changes they did to crafting, I lost that skill and had to redo the work to get it again on all the damn classes. It was quick for my main crafters, but for the ones whose cross-skills weren't useful back then and which I never used to craft high-level recipes, I had to go back and do them practically from the start.
