They Call It the Kissing Disease

One allowance here buys 1,245,654 EXP, the best on the Lv 58 Fisher fieldcraft rung — matched exactly by 1 other leve of the 6 there, with the rest trailing at 747,393 EXP or less.

Across that rung the return runs from 124,565 EXP to 1,245,654 EXP per allowance — 4 distinct figures spanning 900%, so the wrong pick leaves 1,121,089 EXP of the allowance unspent.

On whether to wait: the best Lv 60 Fisher fieldcraft leve returns 1,267,826 EXP per allowance, 2% more than the best on this rung, while the Lv 56 rung behind tops out at 1,191,215 EXP.

At Lv 58 this data holds 54 leves paying EXP across 2 categories: the 6 Fieldcraft ones average 716,251 EXP per allowance, the 48 Tradecraft ones 327,945 EXP, which puts this leve 74% above its own category's average.

Nothing on the turn-in list is craftable in this data: Yalm Lobster ×3 has no recipe here, so 3 units must come from gathering, a vendor or a drop.
