OK, let me throw down my two cents about this. I use this daily and it works EVERYTIME, so you can disagree with me, but it works so thats your problem. While your camping the selected NM, DO NOT TARGET ANYTHING. If you have something targeted, the sub-targeter on MrArgus wont pick up the NM and you will spam your macro on the wrong mob or no mob at all. So, don't target anything while camping. Also, if you face north, the way the program works when it warps you, you will be facing the mob directly and ready to go at it. Once you have casted a spell or a JA, it will show that you are targeting, but up until that point you, you are subtargeting, which doesnt show that you are targeted but you actually are. So try that out, it works for me.
