Absolutely essential and NOT CHEATING, imho. I think it is common sense that your characters know how to use their skills and react to the battle around them. You should be able to focus on playing your own character and only have to manually control each step in certain, key battles.
It should slightly reduce skill points though, as this is tied to a skill tree, so it would essentially eliminate a skill tree and leave you with more skill points for other skills. Just the balance freak in me speaking
Also, I don't see the need of the "no blood" mod. There is an option already in the UI to disable it (which I did).
