Remember the other rules.
3 nacelles are out(AGT-Galaxy was a special case. Something about 3 pairs. so 6 "nacelles" in all?).
Has to have 100% visibility from the front.
Bridge must be at the top of the saucer.
Ambassador class has nacelles which are slightly obstructed by the saucer. Violates the rules which mean we can't have that ship in game. :p (just teasing)
And so does the Excelsior. Really the worst offender. and the refit got impulse engines in front of the nacelles...
Saber class is shady. Does its nacelles have 50% line of sight between each other?
Promethus is another one. (the lower nacelles)
Defiant. Does it even have a saucer so to speak? And nacelles are probably not looking at eachother much either.
The Raven. Well it is a starship. Nacelles wont be waving at eachother any time soon.
And the Negh'var is debatable at best. Only it's lower half of the nacelles seem to have los.
It's such a split up nacelle.
Just to add to the list, the sovy in the game has its nacelles leveled with the saucer when it is clearly in movies, shows etc the nacelles are higher. I have already mentoned this ont he starship whatever error thread but none of the devs have said anything.
As for the excelsior refit, i never understood why they added the two extra impulse engines where it can burn the front part of the nacelles.
