Looking for help with my Laser Commander build. Aim will be to use predominantly laser weapons to make the most efficient use of ammunition and perk choices. Here's where I'm at, for reference I have all DLC.

Close Range/Indoors: Tri-Beam Laser Rifle [GRA] | Laser RCW
Mid Range: Laser RCW | Laser Pistol [GRA] (for critters)
Long Range: Laser Rifle [GRA] (all mods except beam splitter)

A couple of questions I have.

Is the Laser Rifle effective long range with a scope and efficient cells vs enemies such as deathclaws?
Will the Tri-Beam and RCW have too low DAM to be relied upon in all close range situations?

Any hints and tips related to S.P.E.C.I.A.L, perks, armour and gameplay in general appreciated.
