Well, I have nothing against these maps. I really like good PF tracks actually. I was just fearing it would go as far as on Nations Forever Exchange. (Every time I visited that site, there were at least one or two PF tracks on top of the BOTW. ^^)
I can think of them just fine, I don't see what the added value is of making a FS in an environment with no high speed walls as opposed to one with walls. The new env doesn't enable more options in terms of FS building, it only takes away options.
