4) Modified FB1/FB2 standard - 1 thrust point rotates to any heading,
BUT only ONE rotation maneuver allowed per turn... in other words you
can rotate for maneuver purposes and then thrust, OR thrust and then
rotate to fire, but NOT rotate/thrust/rotate.....
b) I haven't played this but dislike it in theory.
This has very nearly the same effect as using MD2 drives already has
in FB1/FB2 Vector: with MD2 you only have 1 thrust point to spend on
manoeuvres, so can't make more than 1 rotation per turn. When flying
ships like this most players I've played against choose to maximize
their opportunities to shoot - which means that they'll use their
single rotation per turn to keep the enemy in arc, essentially
forfeiting their ability to manoeuvre except for Main Drive burns in
the direction they happen to face either before or after the rotation.
Basically, with this concept the differences between different MD
ratings become even smaller than they are in FB1/FB2 - MD2 ships are
still just as able to keep the enemy in arc as MD6A ones are, but now
the MD6 ship doesn't even have any noticable advantage in course
changing ability.
