My wish is: more paper - rock - scissors balancing.
I mean:
BS with anti-BS cannons are great against BSs, not fighters.
BS with many Flaks / Flak Cruiser / Flak Gunboat are good against fighters, but can't handle capships.
Bombers are great at taking down all capships and take lower dmg from flak fire.
Interceptor VHFs are great at taking down bombers, but suck at capship killing (they might be able to evade capship [not flak] fire indefinitely, but can't really deal enough damage to take down BS).
I think there should always be a class of ships / weapons good at killing other specified class, but easy prey for another specialised class.
It's quite easy to achieve such effects:
1. Anti-BS turrets for Capships with beam effect (oh, my love for freespace is so great) - they need a 2-sec load time after pressing fire (and they hit place targetted when firing, not actual, no sniping), so they are useless against fighters, but after that load time they deal very heavy damage. BS and capships in general gain even more armor (like 4x at least), so it's almost impossible to kill one with interceptor guns & missiles, but not that hard with anti-bs weapons (beams & torpedoes).
2. Better Flaks - make classic flaks use no ammo and I think they will be great anti-fighter firing solution.
3. More torpedoes with much heavier damage but even slower. Coal torpedoes name change to Coalition Nuclear Torpedo. Soviets like nukes! Make anti-flak shields for bombers, which are great at reducing flak damage, but suck against any and all fighter weapons.
4. Interceptors and Space Superiority Fighters are quite ok right now.
This way we can achieve really tactical fighting, not "let's rape this BS with fighter guns only". If we are going to have easier cash-making, then ppl will be rich enough to build up specialised wings.
Tactical battles with coordination via TS would be so EPIC... like...
"Interceptor Squadron, we have Nuclear Alert, intercept that bomber wing before they get to us!"
or
"Command, this Flak Cruiser is pummeling us hard! Requesting fire support! / Rgr that Alpha Wing, plotting beam firing solution, clear the target!"
Ah, dreams! Y u no come true?!
