Tagging energy weapons is a choice, you could also have tagged "gambling" and struggled even more to find good use for it. Tagging energy weapons is something that pays off later. You must wait for it, like desert after dinner! Me, having started with the old games, and moved to the new, I react the opposite way you do It has a lot to do with expectation - I expect laser weaponry to be almost non-existent, so rare it borders legendary. During my typical FO1-2 play, I will give only a few points to Energy Weapons, now and then, as I progress - and eventually I'll "tag" it with a perk later on, significantly boosting it for when I finally get my hands on one of these epic, technological marvels. My first experience with FO3, and the laser-pistols pretty much dropping in your lap right away, I felt ripped off! To me - that was the flaw, the weakness. You had different expectations, so you see a different flaw.
