Improved Shield Block

Improved Shield Block extends the Shield Block ability to block attacks, reducing the total damage taken by the Warrior.
==Functionality==
Shield Block normally lasts 5 seconds, or 1 hit (whichever comes first). Improved Shield Block extends this to 6 seconds or 2 hits (whichever comes first). There is only one rank of this talent.
==Notes==
This talent is highly important for an endgame tanking Warrior. According to combat parsing, it's been more or less proven that achieving very high block rates pushes crushing blows off of the combat table. (See .) And this talent effectively doubles the number of hits that will be blocked. Spamming Shield Block with this talent means that almost all attacks will be misses, dodges, parries, or blocks, except with very low attack speed mobs.
