Current economy is broken due to the fact that players get infinite weapons and armor from encounters.
Let's take for an example unity encounters (one of the most farmed),if players kill too many unity members then there would be less unity encounters, if they killed too many rouges then there would be less rouges encounters and there would be less unity vs rouges encounters.
And remember that there is a bunch of players who just want to login on evening and fight. You can't just ignore their existence. There would have to be some alternative for them (Hinkly isn't enough).
All that will accomplish is having one faction hoard everything and even further imbalance pvp.
The reason factions stockpile guns and ammo is you need those stockpiles because of constantly replacing gear without delays, adding more things to spend money on won't change that. There is no large newbie population and there probably won't be, anyone who's heard of this mod and is interested has already checked it out. No one sells junk because its time intensive and the stuff is heavy and worthless for anything other than bases. Only a sucker spends hours working for someone else in this game.
