The Tradecraft large scale leve quests are even worse than the Fieldcraft ones. Compare the following two leve quests:

Like Lemon on a Lumbercut (L): Carpenter, Lv. 54
Costs: 10 leve allowances
Requires: 5 dark chestnut lumber
Rewards: 78624 EXP, 994 Gil, potential crystal rewards (mine currently shows 24 wind crystals)

Walking on Pins and Needles: Carpenter, Lv. 54
Costs: 1 leve allowance
Requires: 5 dark chestnut lumber
Rewards: 78624 EXP, 794 Gil, potential crystal rewards (mine currently shows 12 ice crystals)

Given that the turn-in requirement and EXP reward are identical, that means you're spending 9 extra leve allowances to gain 200 gil and 12 crystals.
