Help with setting up NPC fight?

[nclsdv]

The popular method to set NPC fight:

 

1) Turn tai, tcai and tdetect off

2) player.placeatme <BaseID> <amount>

3) Turn tai, tcai and tdetect on

 

The problems:

 

1) NPC aren't as strong as when you encountered them in-game (Ebony Warrior, Miraak, etc.) By using getlevel on them, I get value >> 0, which I think means really weak NPCs.

2) Some NPCs don't join the fight.

3) Some NPCs don't attack everyone in sight (Dragon priests don't attack each other).

4) Alduin having multiple BaseIDs.

5) NPCs aren't positioning the way I like (maybe standing in a circle facing each other?)

 

The question: Can anyone help me solve all these problems? I want to battle all the final bosses in a big field at the same time, but at the moment they're just too flimsy. Thank you!
