Yea, so dual wield generates a ton of TPS. The shield is actually pretty garbage in most 5 mans, for most pulls - especially if you are using CC and potentially only tanking 1-2 mobs to start out. Keep in mind that block increases in value based on the amount of mobs in a specific pull. From my experience most tanks over value the shield, leaving it on during their entire dungeon. I'd rather have a tank play a bit more aggressively so that packs can die faster and he can take less damage overall allowing the healer to sit and drink quickly so we can continue to pull. Just my 2 cents

Bumping an old thread because I got some questions about this for a buddy leveling a warrior. He went prot spec at level 40, and I already told him he dun fucked up.

How do you play a dual wield warrior tank? You're still sitting in defensive stance during every encounter for the threat multiplier, right? What does your attack rotation look like? Just stacking sunder armor on mobs? Jumping into battle stance to hit things with a thunder clap and then back into defensive stance to keep swinging away and hitting sunder? I get how shields increase in value as the number of enemies hitting you increases, and I understand why they're really not needed in most encounters. I'm just struggling to understand what you're doing with your dual wielded attack while tanking.
