I switched from controller to mouse/keyboard about a month ago. I'm still adjusting cause I keep rearranging stuff. But I just target using F1-8 keys. I also tried having a cure macro for every single person. The /ac "Cure" <me> - <8>, for Cure II as well. That is what made me fumble. Having to adjust to who was in what slot each time. Even after putting the tanks and the top in my party list.

I had also tried the MO macros, but maybe I'm not coordinated enough; I had trouble moving out of AOE stuff in time. I would end up choosing between me living sometimes, and letting someone die while I moved the cursor off the party list. It was too hard for me to break the habit of moving with the keyboard instead of the mouse.

I went back to easier dungeons to experiment with what felt most comfortable to me.
