this is only my opionion whether it is humble or not who cares
weapons tech tree should have been like this
light weapons
lasers
phasers
disrupters
heavy weapons
plasma
photon torps
heavy disrupters
other weapons
missiles
maulers (for anyone who doesn't know what that is it is a ship wrapped around a weapon at least at the start of the tech it would allow a cruiser to take out a dreadnaught with one shot, of course that would be all it would get)
you would get to choose one weapon from the light and heavy catagories ie start down that tech for normal research, and production costs
if you decided to research another weapon class that would cost you double and a third class would cost you triple in the light and heavy weapons lists
the other weapons list would just be expensive all the way round
ok i have had my say it is now time for the na sayers to have theirs
and i know it is probable to late to add to any version of the game unless you can mod it in which i am not sure you can or can't
