I know I'm a little late to the party, but I've had some issues with Staff. Mind you, I'm only around level 40 in Staff, so I imagine some of my gripes will be managed by gear/skill levels later on.

For right now, I'm trying to come up with a "Tank" build. Combining Staff's extra aggro, damage reduction, and mitigation to keep things from beating up on my wife (who plays as a healer).

I've been playing with Shield for the last couple of weeks and it seems to work 'okay.' It doesn't wow me, doesn't really do much to keep things from wanting to go after my wife (the aggro from 'Fight Me You Fools' seems lackluster), but it works pretty well against bosses. Basically, I was just wondering if there was a different skill that I might be able to pair with Staff that might function well as a good defensive tank build with good aggro management.
