Story time, if you aren't interested in MP AAR just skip this part:
So I played a MP round with a buddy who always plays Hiveminds, as he was this time again while I myself tried out Agrarian Idyll.
As the game went on it became apparent that his empire was better in every single category, even though I was spiritualist/pacifists and tried a unity focus he was even in that far ahead of me, also he was constantly gnawing bits off his neigboors, something I couldn't do, in fact I couldn't even turn my direct neigbhoors into allies because the ideology war goal was still bugged.
So I decided to found a federation with his neighboors, keeping him from expanding and getting me some allies and foremost the sweet, maintance free, federation fleet. I invited everyone in the galaxy to the federation and soon we were 5 empires who could kinda rival that "overwhelming in everything" hivemind in fleet power, if we built the fed fleet to cap.
Thanks to an observation outpost I could see his capital and saw a fleet of 180 Ships there with around 50k fleet power, I didn't think any more about it, which later showed to be an error on my side.
While I built up my economy to finally be the federation president, he started to spam gateways near all the border systems, always one system into his territory.
Once I turned federation president, I started to pump out ships like crazy, using up the stockpile of alloys I built up over the last decades, I designed different ships and integrated all classes of ships into my fleets and the fed fleet until I was sligthly above my fleet cap and maxed the federation cap which meant I got around 65k fleet power combined without my allies fleets on which I didn't want to rely.
I checked his home system and the fleet there didn't change much and indeed, his fleet power showed as "equal" in the diplomatic menu, I got to build a gateway near my capital which could reach all important planets in less than three jumps aswell activate one gateway in another system where one of my shipyards was stationed.
With that in mind, the plan was to attack on the side farest away from his capital, while hoping he would do everything to defend his territory instead of attacking my systems. Once I got through the heavily defended border system, I would continue to his gateway system on this side of his empire, the next gateway would be around 8 jumps away which meant I could take a swathes of his systems and a few planets and then hopefully defend until I could push a status quo.
I did the claims, I declared war, we paused the game because he REALLY didn't fancy that surprise blitzkrieg.
My fleet entered his border system, defended by a bastion with around 30k fleet power, reinforced by his now 68k fleet (did have the harmony traditions and build rapidly ships) consisting solely out of corvettes...
As I mentioned, I saw his 180 ships fleet earlier but didn't think much about it execpt "Whoa, rad fleet command limit" so it SHOULD'VE not come as a surprise and I SHOULDN'T have around half my fleet being battleships with artillery cannons/tachyon lances.
To make matters worse, there was a constant stream of new corvettes ariving from his gateway system, as he was quite passive I decided to lure him out from under the bastion and flew around it to the jumppoint to the gateway system to disrupt the stream of corvettes, he decided that was enough and attacked me and we fought without the bastion doing anything.
Suprising thing number 1: Even though his corvettes were build with torpedos and I had a battleship focused fleet with waay too few PD destroyers, a focus on shields and made to fight mainly other battleship fleets which meant about 35% hitrate compared to his 76% hitrade, I won this fight against a fleet with superior fleet power.
He is quite a powergamer, as I am myself, and I suspect he read what some dorks here on the forum keep repeating: That Corvettes are superior to everything, I can NOT confirm this, seriously. I lost a lot less ships than he did.
So after that first fight, I took over the bastion, repaired my ships there and reinforced my fleets a best as I could, I had not nearly enough alloys though and knew I couldn't keep up that fight very long.
Than I decided to take the gateway system, and sure enough he was already back with a fully reinforced fleet pumping out friga.... corvettes like Goonswarm 2007 did, I beat that fleet again and took control over the system just to notice:
Surprising thing number 2: The owner of Gateways can still use them, even after the system is occupied by someone else. My plan was to reinforce my fleet through the newly conquered gateway but there I sat, with a hivemind as an enemy whos fleet didn't get smaller but bigger each encounter AND could jump in next to our border at any time while I hadn't any alloys left to proper reinforce my fleet and I conceded.
TL;DR
Gateways as they are currently have no drawbacks except the one-time cost, while giving you HUGE benefits in trade aswell as war, I think you should be encouraged to defend them and not use them for some kind of "defend in depth" tactic. They shouldn't be a no-brainer for any empire with enough resources but also be a liability in case the enemy can seize them, even already in the war and not only after the enemy already won the system.
