Here's what I would recommend at 60 for any warrior who's gearing up in 5-mans (this includes dps wannabees, man up and start tanking and enjoy instant groups):
http://db.vanillagaming.org/?talent#LV0LZihzZxizsxMzVoThis spec focuses on the most valuable talents in general while omitting extremely situational stuff like imp disarm and not wasting points on pitfalls like anticipation.
Fury Tree:
Piercing howl will completely change your playstyle since it makes instance trash a joke. It suddenly becomes really hard to fuck up hard enough to wipe. Some random pug ass pulled 3 packs? No problem. Imp demo shout is also a very good tank talent and you only need 3/5 to reduce mob ap to 0. Booming voice saves some rage, and increases the range on your AoE threat ability -- demo shout.
Arms:
4/5 TM is practically mandatory if you care about being a good tank i.e. damage soaker at all, 10% damage reduction through thunderclap is too good to pass up. Deflection gives more than double the avoidance of anticipation so every point is put to good use here.
Prot:
Regarding the argument made by zman, imp revenge stunning a random trash mob and hurting your rage gen simply isn't of much relevance unless you're in t2 gear, which isn't the point of the thread. You can hold aggro just fine in 90% of pugs with the bare minimum of using revenge (5 rage) and shield bash (10 rage), on top of that you can rely on imp taunt/challenging shout/mocking blow.
Imp sunder is bad most of the time since you never need to use it for threat. It's only when the armor reduction becomes relevant that it sees any use.
Mobs don't fake cast, imp. shield bash is bad.
Imp. shield wall. It sounds good on paper, those 5 seconds could prevent a wipe or give a bad group just enough time to kill baron after 6 attempts. In reality though, it's a 30min cooldown and it's already strong enough that those 5 extra seconds are irrelevant 9 out of 10 times.
