General weapons should on be used by the ai UNTIL they have their race weapons. I don't particularly want to see the centuri using particle cannons II when they've got ion torpedos researched and ready to use.
I myself as EA use particle weapons untill i get laser weapons, then i only use laser weapons untill i get Laser/pulse weapons up to the same standard.
I usually only research weapon wise:
particle,(advanced + normal) laser, pulse, balistic, point defence As these are the EA's "weapons of choice"
