An issue I've found, regardless of build, regardless of save, the Ballistic Weave is an essential gear upgrade(unless ur neked). It being bomb-asf isnt the issue at all, but the fact that a game save without it is drastically hindered in terms of Damage Resistance. This isn't a bug or a glitch, albiet vague to obtain, the Ballistic Weave is an upgrade that will most likely accompany your character throughout their play through.
This topic is asking if it would be possible to implement the Ballistic Weave in some form of DLC or perks/update?
Granted this game has your player deal with any and all choices made in-game, including certain storyline endings that may render the Railroad...unreachable. But if you dont experience one of the fewer to find bugs(Nick Valentine ditched my ass), then you've probably trampled over other NPC's new limited dialogue system in an effort to progress.
I'm hoping this will call to attention the void of problems long term players face in Fallout 4, most specifically, the added availabilty of BAMF-tier Ballistic Weave to any player with the Amorer 4 perk?
