Looks like all tank threat was increased 20% today.
As for your build:
Instead of Swift Avenger, You can think about going with Stormgarde with 3 talents in Static Shock (take them from Deflection because since you are not using a 2-hander those talents are not in effect) and Lightning Shield (maybe remove Demoralizing Shout). Change the 2 Taunting Thunder Clap to Natural Disaster and either one taunting Shield Slam or one Improved Sword and Board.
