Dude you are just arguing to argue, and have not given the new system a chance because in your mind you are married to the old klunky one. The new system supports nearly all of that without the clunky repair and assembly and inventory headaches. Every weapon has random stats except crafted ones, they are middle of the road.
1-600 was just a large number that scaled to the same thing we have now with a 1-6. They have a seed and range of stats within a range.
Each WEAPON find is now exciting, for the same reason each weapon part might have been, again without the klunk of assembly and micro maintenance and inventory clutter.
A16 parts were in no way exciting other than the potentially assembled weapon which we now have. They don't even begin to compare with the excitement a mod can give. Mods will be getting overhauled in A19. Possibly random stats on them, or legendary mods and weapons. What we have now is awesome, and its still not the full deal.
