I think these need to be adjusted. I just tried a fieldcraft one for the first time today.

1. It seems pretty bland that they're exactly the same as regular fieldcraft leves, just a bit longer. (Ex. Gather 50 x instead of 40.)

2. The reward doesn't justify the cost. One of them actually rewarded less, with bonus, than a regular fieldcraft leve with a bonus. This should never happen.
LS w/ bonus: 94,000 (difficulty, speed of completion)
Regular w/ bonus: 97,000 (difficulty, speed of completion, +25%)

I'm sure there was already another thread about this, but they focused on battlecraft I believe. But the very fact that a 1 allowance leve awarded 3000exp more than a 10 allowance leve is a clear sign something isn't right.
