Since TT will be released soon, and Slayer is next, I would really like to see experience monitoring being implented, together with better ranking highscore, so you are able to view your current rank in total levels on your profile and if you click a skill you are transfered to your ranking in that particular skill directly, this will make it easier to navigate and promote people to "compete" as they are able to more easily view and compare against one another, think of it sort of a carrrot to keep players motivated to continue progressing in experience or better k/d ratio, etc. AND finally add exp monitoring in the game itself to track skills, tasks-done or k/d for current session.

Down below are just some examples on how it could look like. (it doesn't need to be fancy)
