Yeah, the key here is when the rested exp bonus is applied. When you kill something, rested exp. When you discover a new area, when you finish a quest, when you complete a challenge log objective, when you complete a hunting objective... none of those apply the rested bonus. However, each time you gather something does use the rested bonus. Each item you craft uses it(cotton to thread, thread to cloth, cloth to shirt - a single finished item could use a half dozen or more rested bonus hits). While out fighting, many people arent typically killing everything that moves - theyre killing the ones they need to, the ones in their way, and the ones that attack them first then going back to update quest objectives. If i have a quest to harvest 30 logs(or need them for some carpentry i plan to do) then im using 30 seperate rested hits - more if i need high quality.
