In DCUO they had score cards that told a little bit of everything about the "dungeons" we'd do.

Damage in, Damage out, Healing In, Healing Out, Power In, Power Consumed

It was a pretty nice tool to compare yourself with others, and competition cane be a good thing.

And we need VOICE chat badly. DCUO (sorry to reference again) had it, and while it wasn't without glitches, it was a great tool. At the moment using three different second party chat software on my phone. Seems like we should be able to put something in the game that everyone could use.
