Hi I think it would be much more beneficial to servers and the way people interact if the clan tag was not visible players outside of that clan. It removes so many strategic opportunities to interact with others, deceive, or work together in different ways. Who you are with and how many members you have online is a strategic advantage and so highlighting that seems like a miss.
Perhaps this could be revealed if you scout players and follow them back to their base.
Just my thoughts right now.
