To make it easier to level professions to 800, most recipes will stay orange for 20 more points. This is a huge change! For example, the blacksmithing 780-800 part needed around 120 Demonsteel Bar and 60 Blood of Sargeras at minimum to craft 30 Waistguard. (you probably needed to craft 50 if you were unlucky). But now you will only need 20 Demonsteel Bar and 10 Blood of Sargeras to craft 5 of them.
The rank 2 recipes have the skill ranges that the rank 3 used to have, so if you are really unlucky with the rank 3 Alchemy recipes, now you can level Alchemy to 800 with just the rank 2. Or you can level inscription to 800 without waiting for the Darkmoon Faire.
It seems engineering helms are the only one that didn't change because the helms were already yellow up until 800, so engineering was already easier to level than the other professions. But now with this change you actually don't even have to make helms, because you can make the previous recipe up to 800.
