I can understand some tweaks to the troop colonization bonus. Specifically, I would have preferred decreasing it a bit and trying to get the AI to use it more.
The problem with this now, is that there really isn't any race left, is there? The country that gets there first is the country that gets the province, just like in Vicky 1. No real need of enabling multiple countries to colonize in one place, even. I'd like to see some means of aiding speed, so that there is a possibility of a country jumping up from maybe as much as 20-25% behind. Let there be some excitement about it, without it being a game breaker...
Yes, the fact that multiple nations can compete at colonisation is completely obsolete now. It also makes no sense, why would placing troops in a province NOT help pacify the natives in your favour? It was more historically correct that way. So the verdict must be laziness.
