1)
Add a feature that can upgrade a part in an extra tab in the shop?
The user could upgrade, say, gun damage by "x" amount of points (gun damage in this case, TG if it was a ram arm or such). To upgrade the part, you have to stick it in a certain slot in said extra slot and insert, for example, 1000 bot stract for one use of the "upgrader".
Each time you try to upgrade, the amount of points changes randomly so it could go lower. (to reduce the bs amount even further, make it difficult to get a high value item.) You can keep doing this until you create a good item.
This could burn the bs quickly and also, if a good part is made and sold, it could reduce the hefty amount of gigas everyone has.
2) when playing a game, pvp or otherwise, have a tick box in the lobby saying "I wish to use bs". However, since this is advantageous to you, have it take off a percentage of the bs (or a fixed number) everytime you play.
This way, the game should be fair because greedy people who want to keep bs make -for example- sector games the difficulty they should be, without the additional power of the bs. But also, those who aren't and wish to use the bs in the desired game mode, lose bot stract. In a situation such as an intense pvp match, playing with bs would cost them bs.
Hm?
