This is a fan site so you can't directly address Blizzard here (even though a blizz rep might be readin this, who knows).
Do you have any ideas on how to make the sword and board passive better? I think if you would present some of your ideas it would open up a discussion and people might post possible suggestions to make the passive more appealing. I agree that it sucks at the moment but personally, i don't feel like a barb shield build is missing from the game.
However, if they do want to buf the snb passive, i would like to see something that makes you even more tanky. Something to make up for the lack of a second life passive and somethign to compliment any zdps / tank barb build people might come up with.
