There isn't one person working on the game. It's a team of developers who have their own portions of game design they are responsible for. So the person testing and balancing weapons is not the same person who would be working on vault space or fixing glitches. Game design is not a single file line. So saying something like "why do you spend time netting guns and not adding vault space?" is a bit daft. That said, we all want them to fix the problems in the game, but these changes don't really have anything to do with that. We'll adjust to the weapon changes and it'll be fine.
