I came here to post about this as well.. last target should under no circumstance be yourself... you have a target self macro for that
. This way if I'm fighting someone, I can heal/cure/buff myself, and then continue casting on them, without having to re-set the macro (which could be an extreme pain if you are having a running pvp battle). I believe this is how both the UO client and UOA work, and i think its the best way. Thanks, i would love you for it
