I have the eldar codex, no need to throw lexicanium at me. Just as easy to open the book I know the fire dragons use fusion weapons, thats what I mentioned, didn't I? Well okay... I forgot harlequins use fusion guns (or pistols actually). Also Las = Laser! And force/power weapons are not that common, most are still shuriken or laser. A TT-eldar army usually has over half of their weapons as one of those.
Misread your edited part ahahahaa, I read as if you wondered if the fire dragon weaps are Melta or not, my bad mate of the MYST!
