Hi guys first time player here.
Started a couple of characters and they have mostly been dps and was wanting to learn how to tank and now that im lvl 15 i want to jump in and do it but i have no idea how to tank. so please give me some basic tips or help on how to tank low lvl dungeons.
Warrior tanking is very easy. The key to doing it well is managing your rage, particularly in between fights. You want to start the next fight with as much rage as possible. If you let your rage fall away, you will be fighting flat-footed and your party will eat you alive.
At level 16, I'd talent into Blood and Thunder and Toughness. You'll want to aim for Warbringer as soon as you can, because that will let you start fights with Charge in Defensive Stance (until then, you can only use Charge in Battle Stance, which means you really can't use Charge when tanking). Unfortunately, Warrior tanking is facepalm until level 33 or so, when you can afford both Bastion of Defense and Warbringer.
So, until you reach level 35 or so, you will be pulling with Taunt or Throw. Put up your Rend on the first monster to reach your melee range and Thunder Clap as soon as the rest are gathered around you. This is the only way to pull until you get Charge. Once you have Rend on every monster in the group you've pulled, just keep casting Thunder Clap as often as you can.
At such a low level, you will be using Taunt+Heroic Strike a lot. Someone will pull a monster and you will be required to taunt it back to you and use HS to climb above everyone else in threat on that particular
monster. For a long while, the strategy will be to use Thunder Clap (and Blood & Thunder) to hold the entire pack on you, then "spot welding" aggro on anything that people pull off of you with their own attacks.
Cast Victory Rush as often as you can. VR will proc late in the fight, and between the damage you deal to the target and your self-heal aggro, it is a significant boost to threat when your party is probably using their own procs and coming close to topping your threat.
Back to the rage management "problem". Do not overload a monster with threat, because at some point it represents wasted rage. If you've topped everyone on a monster, tab-target to the next monster and dump a bunch of threat on it, too (Heroic Strike, Sunder Armor, etc). Late into the fight, you might see that monsters die long before the killing player can pull aggro from you, so you'll find a sweet spot where you can start slacking off and "bank rage" for the next fight.
In between fights, keep an eye on your healer's mana. There is a tug-of-war between the two bars: your rage and healer's mana. As soon as the healer seems to be ready for another fight pull again quickly (it shouldn't take long, but you don't want to exhaust your healer, know what I mean).
Running through a dungeon with as warrior tank should be like driving a tank in Grand Theft Auto: if you stop, you die. Keep up your speed, go as quickly as your healer can handle, and don't stop killing. If you keep your rage bar full you can always dump a Heroic Strike on an errant mob, and you will be able to keep casting Thunder Clap like clockwork.
Once you're good at it, you may even be able to drag a monster from the last pack to a new pack and spread Rend to the new pack without having to waste rage on applying it fresh. Once you reach level 35, though, almost everything about warrior tanking changes. When you get Shield Block and Warbringer, you'll need to come ask the forums for advice again
