Kind of second what Svpernova said...

Crit immune is your first priority, can do that talents alone.
Crushing Blows are only by mobs 4 levels above you, instead of 3... so that never happens at max level now.

You'll end up with impressive armor, just by being a bear.

I'd go with Sta over Agi, until you reach a point where you're not dying too quickly for your healer to react.
Once you reach a healthy pool of hit points, prioritize Agi over Sta because that is avoidance and crit and to a lesser degree armor.
