As the title says, I haven't tanked on my warrior since I was pugging ZG and MC. I have been doing a lot of reading on these forums the past day or so and it has been a huge help. I have been playing a priest since 06 and have known nothing about melee combat.
It would be a great help to me if some of you could give me some pointers on my gear and/or spec. I want to start tanking 10 naxx pugs. I'm hoping to be able to start Thursday Night (24th). I have read that I need 8% hit, 26 Exp skill, and min 540 Def to not be crit. I have gemmed for exp using the 8 exp/12 stam gems.
I am feeling confident in my ability to tank, I am just worried about my gear. I am close to the number required.
EDIT: I should add that I have been 80 for less than a week and have yet to start my Hodir quests. I hit 80 in Zul-Drak
Overall for someone who has been out of tanking a while your on the right track.
A couple of things I noticed. Make sure all your gear is enchanted, you have alot of blues and Naxx while not hard by today's standard might prove challenging depending on the PuG you get in.
For threat, expertise is the way to go. Exp > hit, always. But, you may want to focus more on EH(meaning STA) for gemming/enchants at this point. If you are going to be OTing, then the threat will certainly help. But, STA/Def is never a bad choice for survivability. You will notice as you gear up in Naxx your defense will take a hit and it gets harder to stay above the minimum. Try to pick up the Repelling Charge from Thaddius as soon as it's available to you. It will serve you well in the near future.
Lastly, on your spec. You have 12 points in Arms, but did not go for Deep Wounds, to me thats kind of a waste. Also, in the Prot tree you should really take Gag Order, I'd suggest loosing the points in Cruelty. Those points would be better served elsewhere.
The Improved Def Stance (which procs a lot) + 2x One-Handed Weap Spec will give you +14% physical damage (+4% more than 5 points in One-Handed Weap Spec) and less damage from spells. It will also give you an enraged buff that you can use to pop Enraged Regeneration.
And about your gear... You're thinking smart about the stats, but it's going to be hard to start tanking raid stuff with 24K HP. You need 30K+.
Gem for stamina right now until you have enough gear to gem for other things while maintaining +30K HP and 540 def.
Improved Rend is alright, but don't give up Gag Order for it. If you want it...
