What the allowance actually buys
One allowance here buys 565,870 EXP, the best on the Lv 70 Armorer tradecraft rung — matched exactly by 1 other leve of the 3 there, with the rest trailing at 339,520 EXP or less.
On whether to wait: the best Lv 72 Armorer tradecraft leve returns 698,030 EXP per allowance, 23% more than the best on this rung, while the Lv 68 rung behind tops out at 681,530 EXP.
At Lv 70 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 433,208 EXP per allowance, the 3 Fieldcraft ones 1,302,824 EXP, which puts this leve 31% above its own category's average.
Deepgold Kite Shield ×1 is a Lv 71 Armorer recipe, 2 steps deep through 3 intermediates, costing 20 units of raw material and 33 crystals.
Handing that in returns 28,294 EXP and 192 gil for every unit of raw material the order swallows, and the tree needs Armorer, Blacksmith and Goldsmith.
