Longbow build question.

It's I have both the 0w and the 0w2 as well as the hero one but I don't plan on using that one.

I got the 0w2 first and was using 2LRM 20+st and 2LRM 15+st but then later added the Narc and changed it to 3*LRM 20+st.

For the 0w I did a similar build but added the tag.

My question is:

If the AI pilots use them properly so is the tag and or narc useless on AI pilots. I did a weapon group of the Narc on 1 and all missiles on 2.
