My experience with Energy Weapons has been terrible. Lousy damage, hard to find ammunition, less variety than guns and it's also harder to aim because some energy weapon "projectiles" are too damn slow. It went so far that I use Guns over Energy Weapons with my character who has 15 in Guns and 100 in EW. The only good weapon I found so far is the Incinerator, but it's not what I had in mind when i chose EW.
There's a weapon mod for that
I have not tried it as I don't use plasma, but it should help.
AM I THE ONLY ONE... who really hates how laser pistols/rifles have no ironsights!?
They added them to the plasma rifle! (but not the pistol).
Grr.
