My suggestion to Obsidian/Bethesda is to restirct that perk to only plasma weapons or a specific energy ammo.
Like that, a pure energy build could always have the opportunity to use weapons in those critical situations where you need to be precise without hurting anybody else(for example when retaking the NCRF prison, you wouldn't have to worry to damage the NCR sodliers when fighting inside the building against the Powder Gangers or that sniper, if you want to snipe him, when trying to save President Kimball).
