WGs are different. You can find WG on any step (except the last) while not in a BA. BA you can only find on the LAST step (so average cost per discovered BA = (1 / % chance of finding BA) * # of steps in an area * cost per step). In fact this change is favorable to finding WGs since you have more valid WG finding steps. Out of 176 steps in 1-1, before you would have had lost 16 steps in an 11-step area (complete 1-1 16 times, and that last step is never WG), vs 11 steps in a 16-step 1-1 (complete 1-1 11 times, and that last step is never a WG), assuming WG encounter rate is the same (which is honestly at this point a bad assumption). you have gained 5 more attempts at finding a WG in the new scheme, all other things being equal.

You can of course always choose to decline participation in a BA or hold an area until you have more vit, but because the average cost to complete an area is higher, you need to have more vit which encourages more flexible playtimes (or shoes). Declining particiation in a BA of course means you loose the rewards, which means you are likely per resource netting less since you have to find the area again. The only way to really prove this out is to make educated guesses at to the rates (well not so much guesses, BA spaw is roughly 20%, last time I LAW hunted) and run a monte carlo simulation.

I onced tracked an average vit per BA LAW when law grinding (BA LAW only, not counting LAW off AW). I should do so again with the new areas to find where we are. I seem to have lost the data though, sadly, and my memory is fuzzy as to what it was. I'll strive to do so on the next LAW I choose to grind.
