World of Warcraft New Encounter Journal Preview

PCGamer had the chance to try World of Warcraft's new Encounter Journal, which provides full details on the boss fights in the upcoming Firelands raid, and reports their impressions on it:
The new Encounter Journal has landed on the World of Warcraft test realms, providing full details of the boss fights in the upcoming Firelands raid. The Journal is set to act as a one stop, in-game wiki that will provide in depth information on every raid boss, gathering the huge amount of information normally only available on sites like WoWhead and WoWwiki into one official document.

The Journal will list detailed descriptions of each bosses' attacks, and the exact challenges players will encounter in each boss chamber, but will the new addition ruin the surprise of WoW's raids? And will listing every boss attack make them too easy to defeat?
