What the allowance actually buys
One allowance here buys 916,282 EXP, the best on the Lv 45 Fisher fieldcraft rung — matched exactly by 1 other leve of the 4 there, with the rest trailing at 549,769 EXP or less.
On whether to wait: the best Lv 50 Fisher fieldcraft leve returns 963,302 EXP per allowance, 5% more than the best on this rung, while the Lv 40 rung behind tops out at 700,265 EXP.
At Lv 45 this data holds 52 leves paying EXP across 2 categories: the 4 Fieldcraft ones average 733,026 EXP per allowance, the 48 Tradecraft ones 98,250 EXP, which puts this leve 25% above its own category's average.
Nothing on the turn-in list is craftable in this data: Boltfish ×3 has no recipe here, so 3 units must come from gathering, a vendor or a drop.
Revenant's Toll, Mor Dhona issues 27 leves in this dataset, all of them Lv 45, across 4 disciplines.
