My LS wouldn't see even one new member added to the LS if the only change that was made for the neo NMs was simply a matter of increasing their drop rate. Even if the neo NMs dropped 10 of their item, and neo bosses dropped 3 of each. Sure, we'd cap out on the stuff we want sooner, but it doesn't really add incentive to kill higher tier stuff in dynamis.

Most of the existing drops suck for the most part, anyways. The usefulness of these items don't adequately reflect the difficulty of obtaining them. Increasing the drop rate would be like the "fix" they tried to give Dynamis twice in the past by increasing AF2 drop rates. Now there's so much AF2 pouring out of everything in Dynamis that if you've been part of a reasonably skilled LS for a few months, you already have everything you want. But maybe that's what you're trying for here? Just do a few high tier runs, max out, then stop bothering with high tier targets?
