Meeting CSes first is a huge thing in those first 50 turns, but after that, when you have a few dozen total income of each resource, those 2 in capital matter much less. If you use the get 2 envoys for the first 1 sent civic for a short moment, you can also negate the effect of getting the first one for free or not on the road to getting 3 or 6. (which thus effectively are 2 and 5). By the time you get the envoys to really get those bonusses rolling you should have scouted most of the map and met them all. I do still agree that the effect of meeting first in early game is too big, too much a luck factor. And i also agree that the focus on many the same districts in as many is possible cities is a thing, and i think it is unfortunate.
