Feature request: add icons/badges for ranks

[Jay-Karia]

Is your feature request related to a problem? Please describe.

Instead of displaying ranks (such as A, A-, A+, ...) we can display rank's respective icon/badge.

Describe the solution you'd like

We'll add unique icons for respective ranks and display them.
API change: &rank_icon=badge

Additional context

I'll be grateful to discuss about the icons for the ranks.
Can also add different styles for badges.
&rank_style={rankStyle}

This could gamify the card.
