The main things I would like to see is the legal mines and traders closer to each other, You've gotta drive half way (more on some) across the map just to get to the trader after gathering with a processor in between. That is actually more riskier will a hell of a lot less reward considering the drive and getting your nice vehicle robbed during that drive. It's like the map is in favor of the illegal activities, they're all a lot closer to each other.
I don't think things should be the way they were before wipe, as far as prices and trunk space goes, IMO the prices are good the way they are now at least as far as illegal items, however, I do think the weights of each item should have been left alone with trunk upgrades reduced to where they are now. Meth for example, no reason for it to take up 3 weight after processed and each ingredient weigh 2. You can put so much into a zip lock bag, unlike the moonshine, makes sense they'll take 3, they're put into big glass jars.
I don't really post much, but these are some things that I've noticed pre wipe that might make things just a little better. Just my 2cents.
