I had that same problem myself when I briefly used the UAC for hunting. My solution was simple, you lead with jabs and for the most part there is no reason to aim them. So, I made aim clear part of my jab alias. It works well for me and I imagine you could do something very similar. I also change my aim location around quite a bit so I've got aliases set up to change it and just out of habit use them quite frequently even if my aim is already where it should be. I find them handy and you can change your aim location while in roundtime so one could do it then and be ready for that next strike. Other people just make aliases/macros for the different aim locations so all they have to do is put in the creatures name when they go to ambush them.
