Hey. So i'm coming from wow and needing some help to fix problems with my mouseover macros. I'm experiencing some input lag, which i've been told is just how macros are in this game, but more concerningly it seems that 2-3% of my heals randomly redirect to myself. This isn't mis-targeting, or being out of range, or line of sight: I've noted cases where none of those were happening. Here's an example of one of the macros, very simple:

/micon "Essential Dignity"
/actionerror on
/merror off
/ac "Essential Dignity" <mo>

Thanks in advance for any assistance you can provide.
