Guys, the allegiance drop is not always the primary function of the Deliverance Engine

It's not bad for flipping planets if they're far away from the homeworld, but its main use is that it sticks a huge chunk of your culture anywhere. Here's an example of how nice it is:
Vasari culture upgrades give them +11% damage in their culture.
Advent culture upgrades give them +6% shield mitigation in their culture.
Deliverance Engine replaces hostile culture with friendly culture, which means:
- Vasari loses their +11% damage bonus.
- You gain 6% max shield mitigation.
That 6% mitigation doesn't seem like much at first, but let's do some math. Let's say you have your shiny Radiance using Animosity, so it gets shot at for 1000 points of raw damage. I believe it has a base max mitigation of 70%, so it would've taken 300 damage at max mitigation. Now, you add your 6% and it has 76% mitigation, and takes 240 damage. That's 60 points less, or 20% less damage! Add that to the fact that the Vasari lost their culture bonus so the damage output was only 1000 instead of 1100 (another 11% difference), and you gained a 31% damage reduction for a few minutes with one shot of the Engine.
Now consider that along with Iconus Guardians and Progenitor's shield restore, and yeah..
