I have 200 of these things, maybe I can make a few hundred more but I remember when this was quite difficult to make and I still use them only while hunting Terry, Garry and Harry. That being said, should they be cheaper? I have no problem using them at night but using around 6 to 7 on a regular bounty mission (5 stages assuming they are all far apart) is excessive and even my stores will hurt if I do even just 5 bounties. Now I want to make it clear here that I do not want to change their cost per se, I have Zephyr and s/he can pretty much match archwing speed and is easier to control but that's the thing -- it locks me and any other player to stick with frames with high mobility.
I didn't find the right solution from the Internet.
