Destroying the resources they're using to maintain their fleet and the space ports they're using to construct new ones.
If you've completely annihilated all resistance, you've won anyway
I don't know how you reconcile these two statements - that was exactly the point I'm making. These tactics are not threats. They are not an incentive against making giant stacks if the existence of that giant stack wins the war for you no matter how cleverly your opponent plays.
Not correct. You need enough forces on one front to ensure you defeat the forces you're likely to face on that front (while minimising losses to a degree). What's the point in wild overkill? If you attack one empire with 5 times the amount of force you need to destroy them while the other empires are running around wrecking your shit on undefended planets, you're doing it wrong
Did you not read the paragraph you quoted, where I gave hypothetical numbers that are
not wild overkill? 100% vs two 60% fleets on multiple fronts is not an order of magnitude stronger. Splitting your fleet would be a terrible thing to do in that situation - unless there was some kind of incentive that would allow a slightly weaker fleet to put up a fight against a stronger force in some fashion, no matter how it's implemented.
Again, the issue I see here is that Stellaris has absolutely no incentive against not concentrating as much force as you need to minimize losses. Compared with EU4, where you can't quite as easily just smash one front in a war while ignoring the other, or where defensive advantages and terrain can allow a small, well-positioned force to defeat a numerically and possibly tech-wise stronger force.
The fact that such mechanics require additional thought/redesign to justify them in a space setting is not an argument against them being there - if the mechanics would result in a better game, they should be in there, arbitrary opinions on "realism" be damned.
If there's an incentive to limit fleet size, all people are going to do is roll around with two or three fleets together instead of one big fleet
Did you not read anything else I've consistently said in this thread, where I give a suggestion that is based on
a per-combat basis instead of fleets, much like how combat in EU4 has combat width that is not calculated on a per-army basis?
Please do not respond to that last paragraph by talking about how combat width as a hard limit makes no sense in space. You should absolutely be capable of reading this thread and my replies and seeing my position on that.
Agreed. All we've seen so far is a two one sided conflicts against broken AI.
...have we seen two conflicts? I don't have time to watch streams live, and for some reason I've thought the Stellaris streams came out on Thursday. Last weeks stream ended before the war with the Just League started.
