After level 40 you have little to no need to look at the player progression screen unless you really want to look at your medals.
I am personally interested in knowing how much damage the others hunters did or the number of X they did depending on their character. Basically having the ability to see the other hunters / monster stats. It is something else to look at besides your own personal stats and stuff you already know like level and character progression.
You could also be able to see where the other hunters are lacking and give better and more accurate tips.
