2) Thick Hide/Survival of the Fittest - both of these talents are tanking talents. However, think about how BC was 60 - 70. A Fury Warrior could tank instances up to Level 68. A Ret Pally could do the same as well. Normal instances should not be all that hard -- You'll have higher physical mitigation/HP than most other tanks while leveling up as it is. To max out these tanking talents and sacrifice points when there are utility/DPS talents available is not the best of ideas as utility helps you greatly & you will be spending more of your time DPS than tanking while leveling. Survival of the Fittest should be considered of higher value though simply because it does increase your stats and prevents you from being crit (which can be trouble burst damage for healers to heal through).
