Some short remarks on crafting in Mists of Pandaria: One really positive thing is that this time Blizzard was extremely generous with harvesting nodes in the new zones. They are so plentiful, especially for the basic stuff you need a lot of, that it doesn't even matter that they aren't shared like in GW2. If you have problems finding Ghost Iron Ore or Green Tea Leaves, you are doing something wrong, they are literally all over the place.

On the downside Mists of Pandaria has two features that makes life harder for crafting alts. One is the Spirits of Harmony, which replace the elemental crafting components from previous expansions. Motes of Harmony to create Spirits of Harmony drop from every mob, but they are bind on pickup, and thus can't be traded. Thus if you want to craft something that needs those, you need to farm lots of mobs. With an estimated drop rate of around 10%, and 10 motes needed per spirit, you only get a Spirit of Harmony for every 100 mobs you kill, and it's not clear whether all mobs even drop them.

The other problem is specific to some crafts, for example tailoring: The better recipes are in a level 90 area which isn't accessible unless you are level 87 to do a quest, or level 90 to fly there. My tailor / inscriber mage isn't making much progress in crafting, because he is stuck in tailoring, and can get only one new inscription recipe per day via Scrolls of Wisdom. My alchemist warrior is doing a lot better, being already at 600 skill. Transmutation mastery rocks early in an expansion! Unfortunately Blizzard really miscalculated with the gem transmutation recipes: They need Golden Lotus, which is far more expensive than the rare gems you can make with them. :(
