First and foremost, I would like to see the swear filter re-introduced. While I am sure everyone I talk to is aware that I swear like a sailor and worse on Discord, I don't in-game. I much preferred when we saw creative insults thrown both sides instead of the usual basic "fuck off" etc. Or well, at least I'd like to see such basic swearing being used a lot less.
Pobs need to be reworked. New players or even old players keep creating POBs, sometimes cluttering systems with them (New York and New London come to mind immediately.) It's a little bit silly when a POB can be built, fully supplied until it's full HP and then it will decay for 6 months if it's not shot. I'd much prefer if POBs were a rare thing to see which acted as an extreme money sink so only factions that combine their efforts could afford them at the very least.
Systems need to be smaller or at least more packed. Currently, there are too many systems that act as nothing more than corridors for increasing travel distance without anything particularly meaningful in them. Coronado comes to mind, while I like the system, the 85k cruise from Barrier Gate to Inverness seems like an excessive amount of distance.
This may or may not be a hot take, I do not actually care. I would like if capital ship cruise speeds were increased and they were not allowed to use Trade Lanes. It's somewhat funny but in a very "I don't like this" kind of way when I see 5 lib carriers or any other type of large-cap try and interact with trade lanes and then get stuck or wobble like they weigh nothing. This idea also would make me want to dock on a carrier for taxi services to drive my snub into battle.
I already told this to Groshyr and I think Skorak is doing a good job of this, but, I would like to see an increase in storytelling without words. I'd like more atmospheric systems like Zeta or Kepler for that matter, even if Kepler feels a bit overdone overall.
Bounty Hunting needs to be way more streamlined. Currently, the process of this tedious "paperwork" rp is not really worth the hassle of trying to hunt down people, rp with them, and then kill them only to write unnecessary (however short or long) rp just to get your 2-4 million s.c. BHG ID NEEDS the same time of plugin that is used in events for claiming kills. I know that I would personally fly BHG a lot more if I were guaranteed a payout for the effort that I can also then boost by claiming on forums if I can be bothered (I can't.)
Trading. Everyone knows it's awfully dull. It needs to be reworked. The closest thing to a fun trade route was Slappy's cardamine trade route based on vanilla infocards. The usual A to B trading is terrible. I cannot imagine anything more boring than actually trading for hours.
This kind of ties in with the point above. Kind of. Smuggling sucks. It blows large amounts of brown starfish. It is not NEARLY profitable enough to make sense to do it. The risk is higher than the reward. Not so much nowadays due to low pop at times though, but I digress. I'd like to see it buffed and also wish it was more cut-throat between players. Pirates stealing from pirates to make big stonks for free by getting the other player's cargo one way or another.
I can probably think of more things but i am a tired boy who has not slept enough today ):
