Stats for a warrior?
For leveling, Concentrating on Strength, Stamina and Agility are usually all you need to worry about. Agility not so much, but its on the gear. If you find gear with Hit crit or expertise rating, these should be highly considered. DPS and Tanking should be the same gear set for a warrior leveling. Don't worry about defense, just put on a one hand and a shield. Should tank just fine.
Might generally is better for DPS, Kings is better for tanking.
Yes you can bubble the warrior. It doesn't hurt the performance. That got changed a few patches ago. Bubbling them via priest bubble yes, pali, not so much.
He does not in fact need to be full prot, or prot at all to be a good tank tell end game.
Warrior tanking is fairly simple at lower levels, DPS with hate in defensive stance. Don't stand in stuff that hurts. Pay attention to your healers mana. Keep the DPS from being idiots or pulling too much threat (It's a tanks responsibility IMHO to call the shots). Warriors put out hate single target very well. AoE not as well as a pali, but good enough to keep the healer from dieing, and probably keep the dps from pulling agro.
They need to be taking damage to function though. So don't worry too much if you see them taking a bit of damage. They have a few
cooldowns they can use to
save themselves some pain. And those are for any spec. If they feel like taking prot for more
survivability while being able to put out hate, they also gain a nice
oh sh*t button.
::EDIT::
Looking at dudes spec for prot. I'd suggest something a little different. But honestly, just sticking all your points in one tree doesn't work well.
I forgot to add this as well; Armor and Stamina work better longer than defense and avoidance. Warriors need to take damage, to gain rage. They don't do enough damage with a sword and board alone to get enough rage. So working in avoidance on top of a solid mitigation is a good route to take. This is in reference to higher end tanking, mostly. But the concept applies universally.
