They've introduced Bounty Hunter, Duel Tournaments and the Grand Exchange but you didn't seem to mention those changes. You can still PlayerKill, stake high amounts (DT's) and trading is a lot easier than before. The only people who can complain are merchants. But you're complaining because you're a drop trader, which happens to be against the rules. Incase you didn't read all of Jagex's statements, the trade limit was put there to stop RWT, and RWT is generally considered bad.
