Squishy druid

[Donruss]

I spent my first 6 hours ever in the bear pits with a buddy. We had a blast!

However, the Bears taught me 1 thing. I am very very squishy. My gear has always been mediocre at best. I felt like I could charm bats in solB naked if I had to, but these bears are on a different lvl.

I need high LVL druid advice. Are the returns on stamina worth it? Or should I go for hit points mostly? Agi effects AC, but how much? What are some popular "battle druid" items? For example, I see ballers with a sarnak shield.
