I do think a new turret or two would be fun. Not sure exactly which niches are missing, but here are a few:
A "Tesla Turret" could be different from a Lightning Turret, because it's not so much an Area Attack weapon as just something that does much more localized damage to one target, with other damage to a few smaller nearby targets. In that sense, it wouldn't be much different than the Flak Cannon already in the game, but maybe it packs a heavier punch and only hits a few units--or even slows down their reload time for weapons
? No idea how hard that would be to code, but we haven't seen any weapons that introduce any kind of "stun" effect. It'd take a little play-balancing (maybe the duration of stun is in proportion to damage done as % of a ship's total damage), but has that sort of thing been tried before?
Not the Nanite turret proposed earlier in this thread, but I love the notion of a turret that does "duration damage" where it only hits one ship at a time, but that ship will continue to take damage over the next 90 seconds (or whatever) as nanites go to work devouring the ship like termites.
Maybe a "Point Defense" turret that actually has a 50/50 chance of shooting down enemy missiles and also can do modest damage to Swarmer, Light, and Ultra-Light craft? Again, not sure how easy or hard that would be to code the "Missile defense" ability, as it's a new dynamic in the game (I think), but it'd be cool.
I wonder if there might be a way to introduce a Turret that did modest Engine Damage on top of normal damage? The Grav Turret is a nice different flavor than the Tractor Beam Turret or the Logistics Station's ability, but why not introduce a turret that actually damaged AI Engines a little bit?
Maybe even have some Turrets that could only be unlocked by Advanced Research Stations?
Can anybody else tell that, if I were an AI, I'd play a lot as "Entrenched Homeworlder"?
