Quality Decay at the Docks ?

[Refar]

Is it just me, or do the Units you can get from the Docks get worse over time ?

Every game i play, there seem to be better/more specialist at the Docks in the beginning, while after 100 turns or such all i get are petty criminals/servants, while specialist become very rare...

So is it my imagination ? Or are the chances to get a Specialist from the docks decaying over time ?
If so... Why ?!

I noticed it, but I hurry immigration a lot (while they're cheaper than purchasing) and I don't hurry criminals and servants. The result is exactly what you say.

And I believe the first three candidates are usually "good" specialists including a seasoned scout almost always. after them I think the odds are same through play.
