I think that this is an amazing idea, decreasing the price in equipment that is used, for example, in chopping would greatly increase the amount of people doing this to make money therefore increasing the RP opportunities surrounding these interesting roleplay experiences. I think that although it may be a slightly risky move, decreasing the prices of guns, In my opinion may also be a good idea as it makes the weapons more accessible to all players giving them all the opportunity to try weapons that they may have never seen or rarely seen before, for example a heavy weapon such as an assault rifle, I think that not all roleplay that comes out of having heavy weaponry is necessarily a shootout or gunfights, some may wish to RP being a small time arms dealer and solely distributing them or even using them for bank/store robberies. some may use these weapons for kidnapping other players with a weapon more scary than just the average .50.
