Firing arcs and fire rate
First and foremost: I believe CODA abstract systen is briliant, becuse it reflects what we see on the screen.
But for my taste I feel the need of some house rules:
Firing arcs:
* Federation ships usually have many phasers banks, basicaly covering all arcs. So assuming optimal conditions, usually the crew keeps pointing the charged weapons to the enemies (using attack patterns). No change here, maybe eventually for a torpedo spread.
* Klingon and cardassian ships, as I imagine then, are way more powerfull on the frontal weapons and shields, but are weaker on sides and behind. So I usually ajust their maneuver dififculties. As they are NPCs on my campaigns I didnīt bother to write down a rule system, but when the players overmaneuvers the bad guys they receive protective bonuses ("keep us away from their main guns Mr. Helmsman!").
* Some less belic cultures could have even less firing arcs, making possible for ship to completely outmaneuver and avoid their main weapons.
* Maybe Borg Cubes and Space Stations do have 720degrees to aim weapons, but federation shuttles and fighters canīt do much if the enemy is above, below or behind.
Rate of Fire:
* Federation, Klingon, Cardassian and similar torpedoes can fire full spreads every other round. By full spreads I mean maneuvers like multifire. Again its abstract ok?
Its pretty confusing indeed, considering Enterprise-D can fire 10-torpedo spreads, but I believe we have never seem that on screen (generatins maybe?:rolleyes:). I personaly would consider 4-torpedo spreads the "regular attack".
* Romulan Plasma Torpedoes: If you - like me - love the old plasma torpedoes, then i suggest using 2 rounds to recharge. I have no idea why "modern romulans" seem to be using green photon torpedoes, but i prefer to believe that its just stupid CGI lazyness issue.
Plasma torpedoes were originally imagined by the authors as a "Yamato Type" super weapon, slow to charge and very deadly. I like that, becuse its diferent... Itīs sneaky.. its intimidating.... its romulan. :o
Again: nothing above is cannon, or official ruling. :p
But keep something in mind: using different guidelines for diferrent ships make crisis situations more interesting.
