Healthbar script, a social experiment gone too far?

[rIVOLINO]

This script just changes the way bosses are fought, everybody will concentrate at the very last portion of the boss health;
Before the script the last hit was random and there was no need to know the health of a boss before accidentally kill it, they have enough health to avoid those kind of accidents.
Having said that, it is surely useful to purposefully let someone do the last hit.
