Bloodrage - 30 rage in total, 45 if talented, grants a shield equal to 20% of your max hp if using
4p T10 bonus. If not, and not glyphed, costs health
Concussion Blow - stuns the target, used in PvE mostly in dungeons for interrupting spellcasts
Devastate - reduces target's armor and deals growing dmg. Stacks up to 5 times (25% armor reduction). Filler ability, can trigger
Sword and Board
Intervene - charges
friendly target, intercepts next melee or ranged attack against it (not spell) and reduces its threat by 10% (also lowers it's dmg taken by 30% if talented)
Last Stand - grants you 30% hp boost for 20 sec, after this time, the health is
lost.

Shield Slam - No. 1 threat generating
Shield Wall - 60% dmg reduciton (40% if glyphed)
Shockwave - aoe stun and aoe threat generating ability
Spell Reflection - reflects next spell cast on you, doesn't work on raid bosses
Edit: after spending some time on bugtracker, I've found that this skill is going to reflect more than spell if they hit you during those 5 sec. And yes, it should be so. Check this!
Taunt - forces the target to attack you, but has no effect if the target is already attacking you (bad desciption, it's 30 yards range).
Charge - charges the target, with
Warbringer it is usable while in combat
Heroic Strike - adds damage to your next auto attack, causes high amount of threat
Heroic Throw - throws weapon on the target, causes high threat, silences the target
Mocking Blow - causes moderate threat and forces target to attack you for the next 6 sec, no matter of threat
Rend - deals really comparable damage and threat to Devastate; also a filler skill
Retaliation - conuterattacks any melee attack in the next 12 sec
Shattering Throw - 1.5 sec cast, deals moderate threat, but reduces target's armor by 20%.
Thunder Clap - AoE skill, deals high threat, can cause Deep Wounds, reduces hit enemies' attack speed (doesn't work on bosses)
Battle Shout - increases AP of raid members, used when there's no pala for GBoM
Berserker Rage - removes and makes you immune to fear, sap and generates rage when taking dmg
Challenging Shout - forces all nearby enemies to attack you, if you won't gain enough aggro in the next 6 sec, they will go back for their previous target. Doesn't work on bosses
Cleave - makes your next auto attack to strike 2 enemies (3 if glyphed)
Commanding Shout - biggest HP buff ingame
Enraged Regeneration - heals you for 30% of your maximum health
Intimidating Shout - causes 5 nearby enemies to run in fear
What and when
Concussion Blow,
Shield Bash and
Intimidating Shout are not really usable in raids, as bosses are immune to those effects. But, they are great for RHCs.
Use
Bloodrage whenever you can, it's a great rage generator, good both for some burst threat as well as for longer fights.
If you're OT,
Intervene can be used on top dps to lower it's threat, so that MT will have easier time getting aggro
Last Stand and
Enraged Regeneration are most effective when used together, you need an enrage effect before it though.
Never use
Last Stand and
Shield Wall together, that's a waste (unless you really need it, i.e. last 2% of boss and all healers died etc.). Try to use them alternately (together with
Shield Block)
Spell Reflection should be used if every interrupt is on CD (and every stun if target isn't a boss)
Allways start a fight with
Charge, don't be affraid of using it in mid-fight as well.
Heroic Throw is a great opener, use right before/after charging
Mocking Blow should be used when taunt is on cooldown and you'll loose aggro in the next 1-2 sec
Rend is used mostly at the beginning of the fight (because of the 35% dmg buff if target has >75% hp) and if there is at least 1 feral druid (
Rend and tear,
Mangle) or arms warrior (
Trauma)
Thunder Clap - don't bother using it on bosses or even solo targets, unless it's a rouge or something else with high attack speed
Berserker Rage - use everytime it's off cd. From talents you have rage from avoided attacks, BR gives you rage from unavoided ones
