People die at bosses all the time. I think it would be fun to have posted a Kill/Death ratio for bosses. If a player dies for any reason during a boss fight, it would be logged. If the boss dies, it would be logged. These totals would be added up and applied to the previous totals giving a weekly accurate Kill/Death for bosses. I think it would just be kind of fun to know. Give us something to laugh about. Maybe if it can get specific enough, have a section where it marks which player specifically died and have a mini hall of infamy for the players who died the most.
I think a disconnection/leave rate would be interesting to see as well. Anyone that leaves prior to the boss's death could be logged as a disconnect.
