What the allowance actually buys
One allowance here buys 255,336 EXP, the best on the Lv 25 Fisher fieldcraft rung — matched exactly by 1 other leve of the 4 there, with the rest trailing at 153,202 EXP or less.
On whether to wait: the best Lv 30 Fisher fieldcraft leve returns 344,153 EXP per allowance, 35% more than the best on this rung, while the Lv 20 rung behind tops out at 141,630 EXP.
At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 4 Fieldcraft ones average 204,269 EXP per allowance, the 48 Tradecraft ones 31,772 EXP, which puts this leve 25% above its own category's average.
Nothing on the turn-in list is craftable in this data: Yugr'am Salmon ×3 has no recipe here, so 3 units must come from gathering, a vendor or a drop.
Quarrymill, South Shroud issues 50 leves in this dataset, Lv 20 through Lv 30, across 4 disciplines.
