Want to Fix Low-sec? Give it a function in the ecosystem. I.e the main source of direct ISK income (NPC bounties) while NS is for material wealth.
Remove NPC bounties from null sec and increase them in Low-sec. Why are the empires paying people to police lawless space and not their own backyard? Spin the changes as Empires are freaked over triangles and T-space and are looking to handle business at home now instead of abroad.
To compensate Null bears perhaps make the null rats drop more stuff like Ancil repper BPC, strong/improved booster bpc, stacks of 1000 pirate ammo etc in place of bounties. Stuff that has value but isn’t liquid ISk. As a bonus it makes botting slightly harder if they have to salvage.
Make the low end permanent DED (i.e 3/10 complexes) super prevalent in LS. Maybe put a lot more rooms in them with multiple branches to give interesting terrain to PVP in. Make some rooms give buffs/debuffs or maybe make the occupants invisible to d-scan on some rooms. Put SMALL amounts of mercoxit in some rooms but protect them with diamond or burner mission rats and maybe make it so D-Scan can’t see out of the mining rooms. Maybe also buff scan res and scram range and strength in these rooms so that player pirates can sneak up and tackle afk miners/bots easier.
Alternatively or in addition to the new DED sites how about randomly spawning abyssal traces that have loot and PVP opportunities. These new abyssal sites have 27 rooms in the same layout as T-space and the spawning traces can drop you in any room. The exits drop you off randomly in LS or T-space.
Put a L5 security agent in nearly every LS system. These are high reward but require expensive ships to do and are easy to gank.
Remove high end stuff from Highsec LP stores and put them in LS stores only. Require high standings with the agent at that LS station to access the LP store. This way people have to run missions for that specific agent to unlock the LP store. This means risking a mission ship in Low-sec to unlock the rewards.
Put some NPC NS islands in Low-sec.
Put a (very) few sov claimable NS solar systems in Low-sec regions but make them isolated from other NS.
Maybe redesign L4 missions in Highsec to exclusively send folks to Low-sec. Maybe compensate by adding more jump gates into Low-sec.
Put pirate/mordu/syndicate faction Stations in LS.
Make LS gate guns not shoot anything smaller than a cruiser. Maybe make it so they also can’t target Force Recons either.
LS gate guns do massive damage vs capitals and battleships and hit out to 300km. Maybe second set of gate guns that are an FW upgrade that hit capitals harder ( unless you’re in that milita?)
Blackops and JF cynos = yes. Others = No. Dreads/carriers/FAX can use LS gates but supers and Titans cannot.
Remove Ice from Highsec, add more to LS.
Add a FW upgrade to add sentry guns to belts. These still don’t shoot things smaller than a cruiser but smack capitals and battleships hard. Force recon immunity would give much needed love to the ship class.
Capitals can’t be built in LS (but can be built in the new NS islands).
That way NS is about rich mining and PI and the ability to build caps while LS about ratting for ISK and exotic PVP terrain.
