AL questions

1. How good are they at changing a world from a category to another?

2. Have they managed to infiltrate T'au worlds in lore? And if not, what would be possible obstacles?

3. How good are they treating their human and abhuman operatives?(I sorta doubt it is the Salamander-level goodie, but I might change opinion if people can prove it in comments)

4. Do they use more psychic mind control or mind chips for marines not from AL?

5. Could they manipulate a SoB order into attacking the eclisiarchal leadership of a particular shrine world?

6. What would make a tech priest align with non-heretical AL?
