So the game has sort of been stagnated by the fact that everyone does 4 damage types and you can only spin that so many ways between armor and shield tanking. Also, it’s all turrets/missiles. I propose that you bring in some creative new damage-over-time mechanics and direct hull-damaging attacks. This could be done through a new race or two, or through a few new lines of ships for each race.
A new race of ships.
"Organic" race of ships (a spin off of the Triglavians) that do various DOT damage types that linger with a ship beyond jamming/fall off, gate jumps etc. Maybe make “organic” damage a new damage type on top of Kinetic, etc.
That and/or a race of ships that are focused on direct hull damage that transcends shield and armor. The idea being that they use super heavy tractor beams (or whatever) to shake ships and do tiny amounts of damage to ship hulls, ignoring shield and armor. That and/or ramming damage. This adds a new angle to pvp and defense.
A new class of directional fire ships with higher damage but harder to land shots. Make ships that are basically one giant gun that needs to be pointed at the other ship directly in order to do damage (+/- a certain number of degrees). Make ships that have high potential but difficult to land damage. Be it burst damage or something more related to manually piloting your ship and anticipating your targets trajectory. They could be countered by getting in behind their guns and out maneuvering them.
I find the current automated 360 degree system to be sort of stagnant and boring, everyone just orbits and keeps at distance. There is currently some skill in manually piloting but it’s limited. Perhaps even shotgun-like firing systems that can be manually aimed short distances through ECM.
