I assume you are looking for something like in Honor Buddy? I'm not 100% sure anyone really has anything as robust as the CR's in Honorbuddy, but if you look around you will find a few on here for certain classes. I've used the DR CR and Daggerspell.
pretty sure grinder can be set to be used that way by description but i have not used the grinder so not positive. ie you run around and target mobs and it fights for you if thats what you mean.
I am currently working on a Project which will cover this. It can cast Skills and SkillCombos with Priority List etc.
It will support all Classes, as you can add all Skills/Combos yourself to make a Priority based Combo rotation.
I already have a working version, had a little testrun on Target Dummys this morning, but it will takes a while until I put it to Beta.
