I've never understood Bethesda's idea of "streamlining" their games, it's almost never received well by the majority of their community and is often almost pointless. Sort of how weapons were consistently "streamlined" from Morrowind to Skyrim, even the amount of armour pieces you could wear was stripped right down unnecessarily, sure removing left and right pauldrons, gloves and boots was probably a good thing but anything after that was silly.
Although I will admit that at least in terms of armour and weapons they've done the opposite of their "streamlining" and actually greatly improved it for Fallout 4.
