While crafting is fully possible, even doing writs, in full raid gear... I tend to go for the speed aspect... you can crank out a lot more items, more writs, more xp the lower your power pool is... So, I actually take it a step further, and usually mentor down my high level adv toons when crafting, since my crafter army is spread across 2 accounts, and make an effort to keep purely crafter toons around level 6-7 with zero stat gear... If I'm just doing a few items for an order, I don't bother with it, but it does make a big difference in what you can accomplish in an 8-10 hour crafting grind session... which I'll be going through again in just a few months, plan to have at least 3-4 crafters to 80 by the end of the first week if I can get a few days of vacation approved at work
