BossEncounter4 is no longer maintained, you should use an alternative mod instead, such as DBM. Thanks!

Summary

BossEncounter4 is a boss mod and the successor of BossEncounter3.
Its purpose is to ease your time through bosses by providing tools such as timers, health bars, alerts, a radar and other more specialized tools.
BossEncounter4's philosophy is to deliver these tools to the players in a fun, elegant and efficient manner.

Features

Boss modules for Mists of Pandaria and Cataclysm bosses.
Selectable difficulty level. Higher difficulty means the mod will provide you with fewer tools and fewer hints during combat!
Features a diagnostic tool to help players see what went wrong after a wipe on raid bosses.

Selectable health bars for the main boss and its adds.
Timers for incoming events (rather similar to boss mods such as BigWigs and DeadlyBossMods).
Summary window telling you many informations about the state of the fight, including battle rez count and raid alive/dead counters per role.
Visible text for really, really important stuff you may not miss.
A radar which allows you to check your distances and the evil zones of doom which you mustn't stand into.
Other graphical elements are used for some bosses.
Evaluation of your performance each time a boss fight is cleared.

Completely standalone AddOn: no external library or AddOn is required or installed.
Automatic wipe detection.
No configuration to do in long and boring menus. The options for each boss are intentionally limited.
Widgets can be moved and resized. A test mode is available to set them.
Works best with French and English game clients. Correct performances can be expected with other languages.
Includes a bonus feature to check your equipment before a boss, for those who regularly forget to unequip fishing poles...
