Right now user ava-cards only link to their profile page if you click their name. I suggest clicking the badges links to user/Badges, and clicking their reputation links to user/reputation.
I'm often interested in badges for some reason, and it's a click-scroll-click thing from a user's ava-card, where it could just be a single click easily.
Interestingly from the user profile page, reputation score already links to rep.
It seems reasonable that badge displays and rep on the user card also link to their respective pages.
