Yeah, I think that's broken TBH. What I noticed is after I captured a HOP Destroyer and killed one of their advanced satellites - both close to the Flashpoint gate in True Sight, a huge patrol (response fleet) is now sitting around that location, with lots of M3/M4/M5s and at least 3 Destroyers.
When capturing a HOP Construction Vessel on Flashpoint, I noticed a HOP Destroyer and a couple fighters FINALLY came in Argon territory. For some reason, Argons don't open fire on HOP trading ships, and they seem allowed to land and trade, but the patrol fleet intercepted this incursion (that was definitely headed after me), and I jumped in to kill them off.
In the end, a lot of things feel unfinished. You can't transfer crew quickly between ships - have to contact each one individually - so you'll probably never get Elite Marines since it takes forever to transfer them anyway and probably worth using that time to hunt more ships.
Property screen definitely needs a filter, and it's a weird oversight.
NPCs don't seem to gain experience and no way to train them. All NPCs available to hire are 0-skill level, unless you hunt for better ones by landing on L/XL ships since you can find higher level crew there for some reason.
Xenon econ dies off early, by itself. Khaak doesn't seem to have bases or respawns. War doesn't really work. Pirates are very tame and unsuccesful, given the AI. Turrets are pretty borked. Missiles are ridiculously OP, and Capitals have a lot of them. You can carry few countermeasures and Point Defense turrets are pretty much useless.
AutoTraders are very stupid, even if you have a satellite network, they don't ever go to the most profitable trade - they also don't take in consideration the Storage capacity of the ship, so you could have a 10000 Storage freighter doing 900 Storage runs for hours.
Other than all of that and more, again I mention that I feel the world is too impersonal. This game, once the universe/war is fixed, could really make use of systems like the BBS/News boards and things like that.
Just like with X:R, I can see what they were going for, yet I have to ask why didn't they take some 3 months to 1 year to get it all ready. Sometimes I wonder if the devs don't just prefer to release the game on this state and fix it post-release, rather than making a lot of features and content and get exponentially more bugs as development goes by..no clue.
When it comes to Capitals having a ton of health, I'm glad a single fighter can't do anything to them, but flying a Frigate against a destroyer already enables you to kill it. In X:R they were much tougher, and more dangerous if you take out the fact that missiles are OP in X4.
When it comes to stations, I really hope Destroyers main guns can destroy them. Otherwise I'll be mad, since with frigates it would probably take ages to kill one.
I wonder where the game will go in 1-2 years from now, though. Because they could have the best from X3 and X:R.
I haven't gone deep in station building and goods production yet, but I got a Outpost designed super quickly and being able to set building materials prices, budget and hire a builder all from the same screen, along with NPC ships ACTUALLY delivering what you need is just great. If they hit it right in the other things as they did with this, it will get gud.
