Just a few quick questions on tanking,
1, does being crit immune matter pre Heroics?
2, I'm not sure how far I will get with my druid regarding gear from heroics, kara etc, so I'm wondering if its a good idea to stack all my +Def rating gear into as few items as posible? I can craft all 3 of the Heavy Clefthoof set and with all the sockets filled with Enduring Talsites I would have +106 Def in just 3 items (items which I probably won't replace in a hurry) with the neck from CE Strength of the Untamed (+19 DEF) and a Tenacious Earthstorm Diamond (+12 DEF) In my engineering hat (When Primal Nethers are no longer BOP) I would be very close to uncritable.
I could then swap out the Talasites as I found better +def gear.
3, Is it mobs 3 lvls higher than you who can crush you? I read somewhere that mobs in heroics are lvl 72 so you can't be crushed by them, is that true?
