On PC it's harder to get money, on iEra people complain the price of the BAR(200,000$) well, on PC a gun/melee can go up to 2,000,000$. = Economy ruined.
2nd, droppable guns, which make them stop buying guns from the store (as Talon stated). = Economy Ruined
3rd, lack of speed the player has and can get. = PK ruined.
4th, amount of player decreasing. = Players won't play at this point (if it was me, i'd not like to play alone in a server)
