Nobody wants the game to cancel pop growth and claiming otherwise is a bit disingenuous.
What I want is continuous migration that adds to pop growth and I find this pretty transparent, you can take a look at each of your planets and see how much growth you're getting/losing and what contributes to it.
With a discrete system, even if it keeps track of all migration, you will always have questions like, why did this pop move away? Why did that pop come here? And the answer would always be it had a non-zero chance and a dice roll decided it should.
The problem with providing more jobs is that it negates the current use of auto-resettle, if you have an Ecumenopolis or ring world segment to fill just let people on other worlds get unemployed and they will slowly resettle there. And for me migration treaties are a permanent thing and I'm not inclined to change this to make your system work.
You have been arguing in favor of a system with the flaw that I've described. Holding your arguments responsible for the consequences of your arguments is not "disingenuous". Retract or justify that personal attack, please.
And you
have been arguing for those consequences, since they are a direct result of the mechanic you want to keep.
You have no information about relative migration pressure before you sign a migration treaty. Signing one is an
uninformed decision. You have no transparency about the sources of those pressures, nor their history, only about the current sum total pressure at one point.
That's very poor information.
Why did a pop move out? It was unemployed, and the most attractive prospect was not in your empire.
"It was unemployed" is 100% under your control as a player.
"Most attractive prospect" is at worst the same as the current migration pressure system; at best the UI could display the conditions of the destination system at the time and you could figure out why the pop made that choice, e.g. "oh they're running Academic Privilege and that colony had excess amenities, that's higher happiness for the specialist job she took than my Shared Burdens could offer".
Again, if you honestly think this is somehow "disingenuous", please back that up, or please retract the accusation.
