I'm willing to reduce the spawns somewhat, but I think first folks should try to beat it as-is. Try new stuff, try stuff you'd normally think is crazy, etc. Use warheads heavily as if you didn't have anything to lose, that kind of thing. This is meant to be a challenge that requires different solutions than you're used to.
I think the problem with the level of reaction here can be summed up really easily.
You need more force to get the Blade to the Exo-Wormhole than you do to simply take the system by brute force, and the blade it self is no where near enough power to make up the deficit.
This makes me question the point of the Blade itself, finding an ally to help kill the AI that instead makes it much much harder to win? Why do I want to use this game feature? Why would the human resistance want to? The Spire pisses off the AI like nothing else, but The Spire also hand me a very impressive array of tools to help deal with my new problems. The Blade seems to lack this counter balance, no good to go with my downside.
I'm going to have to agree, partly, with this bit Keith. My 2 HW Fallen Spire fleet has trouble getting the Blade to the exo-wormhole, unless its really close entry wormhole where my fleet comes in. And I already know my fleet could take the AI HW in question. I've got 8 Spire Cities. They could stop Exogalatic Strike Forces cold all by themselves if the damn things didn't rush past my fleet to hit whatever they are targeting. Sure I would suffer serious losses, but my FS Fleet is still going to win.
However, I am not sure that simply lowering the Blade response is best for this. You only need to hit ONE of the AI HWs when you use the Exodian Blade. That is a pretty damn serious boon IMO. I've taken out one AI HW with my FS Fleet, lost too much of it and died to the response from the AI before I could bring my fleet back up. And my static defenses by that point can stop CPAs and Waves solo, and even once took out an Avenger backed Exo force. (Granted the Avenger Nuke on Death killed the planet anyway, but my fleet was busy trying to win the game on the other AI HW in that game so I didn't care.) So having to deal with only 1 of the 2 AI HWs is a big benefit, at least IMO. Perhaps the Exodian Blade itself can be buffed. Maybe making it into something on part with a Spire Dreadnought or an Avenger, both in survivability and in damage output. It's supposed to be a Game Ending Superweapon, so I see no real problem with it being on par with some of the most powerful single ships in the game. (Though naturally the GSC and Motherships should still be more powerful) It wont stop the response all by itself, even if buffed as much as I'm suggesting, but it will be a better help to deal with said response. And you can NOT simply keep it indefinitely. The ever growing response, even if capped at certain points before hitting an AI HW, will still make that impractical. Just my $0.024.
