Well, even with the severely dropped Meso rates, dropping the NX items' price to only 1-3 mil will still allow easy access.
Even though it's a private server, NX items should still be somewhat limited, so players still have some kind of items to aim for.
Lowering the 10mil ones to 7-8mil, and either lowering the 5mil ones to 4, or keeping them 5mil, seems like it'll still make the items accessible, but pricey. Because, well, they SHOULD be pricey.
As for having the NX people in the FM... Yeah, I'd like to keep 'em there.
