I was hoping those leaderboards would be an overall time to clear, and also broken down so each boss can have a time as well - at least for raid content.
Having just a HK clear time for example is kinda pointless.
It would be much more fun if every boss had it's own leaderboard for time taken to kill it - I imagine this could get quite competitive.

Most of the other leaders are just crap as they are simply based on time played - it would be nice to see the above to balance things out.
