Really good decision guys, thanks.
Of course the AE changes will greatly de-emphasise the role of coalitions. Nonetheless, I do hope that there is still work being done to them, so as to make them more of a scaling risk/reward soft-cap, than the present hard-cap "anchor on expansion."
I would personally like to see coalitions get harder and harder to beat, e.g. due to scaling military bonuses once the coalitions reach a certain size. I made
some simple suggestions in this thread.
Now that coalitions can be more easily avoided, I think it's even more important to make the more challenging. To summarise my suggestions from my thread I linked: I think coalitions should get Crusade-like bonuses, which start applying after a certain number of coalition joinees (e.g. 3 or 5), and boost the members' morale, discipline, manpower, manpower recovery, and maybe other things too.
At the same time I proposed a removal of separate peace. I can see that this is now less important if coalitions feature much less prominently. Nonetheless I do think they should continue to provide an ongoing risk/reward balance. So I am in favour of increasing the risk - making them much harder to beat - but also increasing the reward when you do beat them. Hence separate peace, or perhaps
sometimes separate peace, like only if you get 100% WS against an individual coalition member can you separate peace them. Or even, you can never offer a separate peace to a coalition member, but they are able to negotiate with you, once they're 100% beaten, because they'd really like to get out at that point.
I also think that they should be brought into line with other diplomatic features, in that they should have some associated cost to members. Such as requiring use of a DipRel. And/or that members of a coalition should need some minimum relations towards each other (perhaps as low as 0.) to prevent odd collections of nations in a single coalition (or add multiple coalition types, e.g. religious-based.)
Anyway, really pleased with the changes and thanks for again proving that you do listen to community feedback!
