The gunsmith becomes almost completely useless after level 15+. I think we should get a reef gunsmith with better items for sale, but they cost more. [spoiler]The only reason I could see him being useful from 15+ is for the Pocket Infinite, but he never sells rare fusion rifles[/spoiler] Edit: Thanks to the people who reminded me that they added rerolling and telemetries that they didn't have before. I'm very sorry that many of those things slipped my mind when making this post. I still wish there was a gunsmith in the reef, but I regret calling out the gunsmith without researching it.
