Instead of Item Level number on a new character stats pane, how about adding proving grounds "bronze, silver, gold, endless" medal next to it?
I rather group up with a good player than someone with big ass item level number. Just my personal preference.
Anyways, this is just a suggestion. It wouldn't take much, just one small icon next to that number.
Let me know why do you disagree with me this time. Always happy when I see that.
