It's important to realize that illusions do not actually give you any sort of faction boost. They simply change your racial modifier and the bigger the negative modifier a race has to Venril Sathir the larger the effect will be.
Right now, the lower your starting modifiers place you on the scale the less points it takes you to reach 'max scowls'.
The short of this is that if you're any of the races that START non-KOS to Outpost then you will not benefit from any illusion the way someone who START KOS.
