Finally, Infuriate, it's good if you must use an IB but haven't enough wrath stacks, or to "extend" 20% mitigation duration(use IB->use infuriate->wait 6 secs->use IB). Then there are "minor" skills like Storm's eye(10% slashing resistance, good for boosting your dps), steel cyclone(moderate aoe damage, useful if you must use overpower/flash but don't have enough TP/MP), Thrill of battle(good for moderate auto heal or for preparing before a big hit, makes Stoneskin and Lustrate more powerfull, tell that to your healers), Holmgang(a big hit is coming and you know that you haven't enough HP? Use this, and then convalescence) and Unchained( dps boost, good for enmity and autoheal with bloodbath).
So yeah, that should be everything you must know about tanking, sorry for bad english and welcome to the warrior side >
