I second this. I'm sick and tired of always getting Unbidden since 3.0. I could manually set it to something specific, but I did like surprise effect and weighting of the old system. I'm baffled as to why devs insist on keeping this change and I fear that this is them not being able to deal with their big mistake (second one after destroying performance with pop change). I think I had about 7-10 crisis since 3.0 and ALL of them were Unbidden. You can't really avoid this tech, especially if you are using something like StarNet AI in order to have AI that isn't braindead.
