The damage ranking is based on the percentage of damage that you have done to the boss. This means that it is easy for you to obtain rewards without competing directly with the other heavy hitters. However, other heavy hitters may take away your chances at earning rewards if they clear the dungeons too fast.
It also means that once your damage pass the 4.1% rank, you can sit back and let the other people deal damage to the dungeon. Simply jump back in for the attempt to land the final hit for the rewards.
Rank F: 0% – .199%
Rank B: .201% – 1.099%
Rank A: 1.001% – 4.099%
Rank S: 4.001% & up
Final Hit: The last hit on the boss.
