So this happened... Fight Lost You were hitlist attacked by *********** with a Fight Boost of 15%. You lost the Fight. You dealt 4937 damage and took 3068 damage. I dealt 1900 *MORE* damage than I took, but I lose?! This happens more often than I'd like to mention. In the immortal words of my mentor, Chip Chipperson.... "Dat don't make no sense".
Typically this will happen if a kill occurs during the attack. You had 3608 Health remaining and their attack wiped you out. If you had a larger health pool at the time of the attack the Damage you incurred would have been > 4937.
