To encourage Raid Finder groups to persevere, each time an Raid Finder group wipes on a boss fight all players in the group receives a stacking buff that increases health, damage dealt, and healing done by 5% (up to a maximum of 10 stacks). This buff is cleared once the boss has been killed.
I guess its sort of ok. I mean I dont think people ever really wipe on LFR bosses more than once.
