From what I saw yesterday the common wisdom that for xp, you should do moderate and difficult *single* WOs hasn't changed. Here's a quick example of why (looking at my notes, those 2 work orders are about the same relative difficulty - mid-moderates, as it were):

Moderate Batch WO
~ 130 xp per item (4Bs, 1C) and 585 xp at turnin (~247 xp/item)

Moderate Single WO
~ 151 xp for the item (1B) and 600 xp at turnin (~751 xp/item)

On top of that, your artisan faction will go up much more quickly. Hell, even the financial rewards are about the same - though of course with the single you don't get anything *but* money.
