Blatant Strawman argument. So in that sense, your post pretty much loses all of its argumentative power, but I'll address it anyways. You have a good point in that you can't simulate a mass of average players and every scenario, but that's why when your new mini-game robs an average player of a 350m cashpile, you give it back. They've admitted fault, but not done anything about it. Jagex should tell players that they can't risk valuable items in new content otherwise the blame lies with Jagex, not the player.
