What I liked in DA:O though, was how it gathered (some?) statistics elsewhere and you could just look who's doing what % of overall damage.
I'd like to see something like that, more detailed even. Overall hit percentages for characters (today/all time), hits taken, kills, damage dealt.
So if you like, you can go and see who's not pulling his weight. Oh, Angry Bob cant hit worth crap with those awesome twin dualblades.
Now, when you say it - it was also a great function. Not an alternative for the combat log, IMHO, but a good addition.
