I don't agree that changing the point system will have an affect on the large farms people build.
It wouldn't help because people have the option to build large farms with 100's of planters , I mean if you could who wouldn't for all that scrap and points, right?
You said it would help to decrease the cost of items, so let's say the heli got cheaper, that one person who had that option to build a big farm with 100's of planters will have a crazy amount of points just to purchase more helis or other items from the black market.
While writing this @alexanightfirehad an excellent reply that I would love to touch on myself.
I completely agree that the black market is here for our convenience, not necessity.
I don't think there is a need to change the teleport to home as @alexanightfiresaid it's capped out at 200, which is actually nice and convenient considering it doesn't take long to get that many points.
While I myself teleport home quite a bit, I've never seen it as a hassle for the points, as I see it as convenient. My favorite thing in the black market and the most convenient thing for me and plenty of others is the minicopter, which cost 1500 points as most of you know. I usually always have enough credits at the end of the day to buy another one ( I usually end up thinking I'm good at flying and sacrificing my poor minicopter to a tree or ground) and considering that I am actually happy with it. Considering I have a way of transporting myself around the map without having to go and buy my transportation or find it I can conveniently type a command and have it delivered right in front of me.
Seeing a change in the black market would be nice to see in the future, but for right now I think it doesn't need to be focused on.
