Hey
@jayroly, welcome to our Community and thanks for using Dropbox!
It's true that, currently, all members and admins of a Dropbox for Business Teams account will take up a license. For more information on the admin roles, you can have a look

If you'd like to show your interest in this, you can go ahead and upvote
this idea, as I think it echoes your query here.
Let me know if you have any other questions!
