Wow, that must have take a shitload of time to make this post. Kudo's!
I agree with HaTe here, I think it should be more rewarding to aim for the head. It was always the strong point of Renegade. By aiming for the head, it was easier to see the skill difference between two players. It made battles interesting and you could win against three / four people at once when you were a top aimer. Ren-X has made that nearly impossible.
