I have to say that your ''but it's so close to reality'' examples don't carry weight (I called them magical lasers because lasers don't work the way they do in any of the Fallout games, nor do plasmas, nor does radiation, nor do bullets... the list goes on), your super mutant example is laughable (growing super mutants is Fallout 3 BS, and only applies to the Capital wasteland ones regardless), and you basically said that less bleedthrough forces players to HAVE to use high damage weapons and high DT armor else they're ineffective which is the exact opposite of the gameplay principle of letting different playstyles succeed. The devs put in 20% bleedthrough for a reason and it wasn't because they threw darts at a dartboard to pick the percentage.
Using internet meme words like ''derp'' is also pretty lame.

Derp isn't a meme but an example of saying how stupid your remarks are. Magical Lasers? they do the same thing as our lasers do, using heat and instant-impact to convey damage, just like: OMG, A LASER!! you know, a hot beam of light from a frequency of color and radiation barreling down on an organic/inorganic substance, thus burning it. Bullets work the exact same thing like in reality does, they zip from the gun, instantly hit against the target, thus doing damage. Sure it doesn't kill a raider instantly when you fire down at someones skull, but the concept is still there. Super Mutant subject? look it up on wikia, their close to 300 years old, both east and west, you fail for not even having to click and look it up before even posting this. No it doesn't, your not paying attention, it doesnt force players to use high damage weapons, it makes the player think and switch to Armored piercing rounds for the target. Boom, dead. Was that so hard? Nothing else changes with the armor except the fact that the highest DT armor nullifies the pettiest attacks, and by the time you have the highest DT armor, you are techinically a demi-god...what's the difference? nothing. With 0% ->10% bleedthrough you actually can relax abit against Raiders and weaker enemies that actually don't scale with you. With 20% your always annoyed by how a simple 9mm can do some damage towards you, especially when they equip rapid fire weapons. The game itself isn't even balanced on what you think, basically showing all the love towards Light Armor, while bashing Heavy and Medium a few times. That's not very balanced now, isn't it?
p.s the 20%bleedthrough WAS indeed a idea, from 15% (which not many people complained about, it was actually pretty decent of DT bleedthrough) to a little jump up 20%. Anything like this is referred to as ideas or guesses on what to tweak in games.
Back then it was actually balanced out (sort of, Heavy actually got the good end of the stick, if they had the perks like now from F:NV, Light, Medium, and Heavy would be a bit balanced then, showing that people with Light could be faster, and get less critical chances of the enemy hitting them with a critical hit, while Heavy armor would increase DR, thus reducing the amount of damage done to you overall)
and Derp came from the term from Basketball from Southpark Creators, came into the slang and urban use, then suddenly became meme.
Basketball-->Slang (actual usage of the word)--->meme. So yes, I'm actually using the term "Derp" correctly.
