If this is a distraction on my part, I don't send more. I jump away if I can, support and constructor both.
I doubt you can, but let us assume you do. What did you gain? You risked a fleet of a given strength to busy an equal enemy fleet. While he may have to move by Warp, judging from the streams we saw, I highly doubt you gained so much of the initiative by this to do anything meaningful. And that is the best possible outcome, if the enemy does not make one of the mistakes you seem to hope for:
Otherwise I honor the fallen for their sacrifice. Either way, let the enemy celebrate victory and waste time exploding the WH station I didn't really need anyway. If I think I can get away with it, I do this again in another area, but for now, I've split their forces and bought time for the rest of my campaign. Hopefully I've built up my forces, hit hard other targets and/or allowed my allies to assemble and arrive in the meanwhile.
So you agree you might lose the Support fleet (contructor is irrelevant). Just to win time. If that's your Goal, you do not Need this wormhole-Station tactic. You could always Resort to normal raiding. And more, you do not have to do this behind enemy lines where you are vulnerable, but in your own space with high mobility due to a well tuned network. If you used well proportioned chunks of your navy, you can easily Keep the enemy busy with them.
But I am relieved that you seem to agree that there is no real Military value in this Action besides keeping the enemy busy and thus winning time. And while this in deed is a valid strategy if you can expect to be stronger later, it is an exception, not a Default strategy.
Additionally, for this Scenario, you seem to assume the wormhole-empire is inferior. If that is true, the enemy may very well directly attack your fleet or domestic wormhole-Network, while you are tryingto set one up in his space (which would do you no good without connecting it to your Homeland). But that is a line of Argumentation,
@Jorgen_CAB already brought up: Offensive Actions when you are inferior do not seem to be rewarded in Stellaris (as much as we can tell already). And wormhole-stationbuilding in the enemy territory definitely is one of them.
On the other Hand, if the wormhole-empire is superior, the Goal to establish a Network is plausible to invade faster and more safe. But then the Defender most likely will do anything to avert this and slow down your Progress by attacking the stations and constructors in his space. So you defend them. Either way, building wormhole stations without significant escort is unplausible.
I'm happy with three outcomes: the enemy sends a lot of small fleets I can take apart one by one, the enemy sends a big fleet that wastes its time, the enemy stops sending ships and I gain a new wormhole station. Either way is fine and the plan doesn't just rely on tiring out the player...wouldn't work so well against an AI anyway.
Each of These three outcomes would be an error by the enemy: Sending too weak fleets that get picked, sending an oversized fleet, ignoring it. The right Option would be to sedn a balanced, but slightly stronger fleet that wins the battle. And in this Scenario, you gain nothing, except the unclear Advantage that you retreat per wormhole while he has to get into Position by warp. Thing is: You had this Advantage before! You always have it.
Sure I can. But the beauty is that I don't have to do that. I might have better uses for my combat forces. Or I have a lot of surplus civilians that I can afford to lose.
But if you have better use for your Forces, who is backing up the construction ship? Despite having the wormholes, you still can not be in two places at the same time. The enemy knows that, too.
And that "a lot of civilians" sounds to me like spamming them to bind the player's (not the empire's!) Attention in Micro.
If we're doing poker metaphors, this is more like semi-bluffing. Your opponent might fold, or you might draw the better hand by the end, but you still win.
If you had the better Hand, you can gain the pot immediately, which is the Station. No Need to reraise for hours with insignificant amounts (relative to the pot, which was my Point). If you say your ultimate Goal was to face the enemy fleet, I respond: You have the wormholes, you can do this anyway!
Note that I assume that the enemy will not just let you have the Station. It would be an error and I can think of no Scenario where it would not be, unless the war is already lost for either side. So if you really want that Station, and he really wants you not to have it (which he should), there will be a Major battle over it. My proposal just involves getting rid of the first stages of the heads-up and start with blinds that are a significant share of each side's stack. But I don't want to strtch the poker metaphors too much.
Start with a noteable fleet size needed to protect thy Station. So it has meaning and eliminates the potential use as Micro-spamming.
Just a reminder: If you say you do not really want the Station but to distract his fleet, I responded that you are binding the same fleet strength to do this, which also is my answer to
@naisel :
The more ships the enemy sends to deal with a wormhole station in their territory, the less ship are bombarding your planets, when you are up against a superior foe gaining time is essential.
