Show rank instead of member group

I wish I could see a user rank instead of a member group in forums and comments. The rank is more descriptive and tells more about user activity and trust than a member group. It has more granularity. But it is quite hidden. I have to hover over the user name to see his rank. When I disable profiles for guests, the guests cannot see ranks at all. And on mobile, I can see a rank only if I open the profile as there is no hover.

Only for the groups that are excluded from the rank system, the member group should be shown.
