We've limited the AI in a lot of ways so I don't think we need to have this insanely low.

Please stop permanently deleting resources, tia.

We planned to do this forever ago then after removing classes from them I just forgot heh.  Theres still nontrivial incentives for killing these.

1.6.6 ai changes
