What if: Arena has a set pool rotation

For public matches, they get every reasonable item unvaulted like infantry rifles, drum guns, flintknocks, etc. Then, Arena gets a separate pool which rotates every so often to keep things fresh. Public matches are where you can play with friends while having absurd strategies and moments to share. Meanwhile, Arena is more focused on developing and evolving the best strategies given your limited toolset. I think this would be a good change for the future of Fortnite, protecting its longevity. But I want more opinions. (Also this probably won't get a lot of karma because this is a text and not a picture)
