Overview

Warleaders are the direct healers and buffers of the creeps.  Their role is to ensure that the DPS classes stay alive to wreak havoc in freep ranks as well as to buff their fellows and debuff their opponants.

Skills

Aura of Command, Aura of Protection are exclusive to each other, meaning you can run one or the other.

Brawler's Stance, and Commander's Stance are exclusive to each other.

The corruption traits are more based on personal style of fighting but for the typical support warleader, maximizing health at the expense of damage and power is generally the best build for survivability.  Critical protection is important for survivability.

Tactics

[Vyxe, Elendilmir]

Warleaders are the support backbone of any creep force with strong recovery skills in both heals and area of effect (AoE) rezzes.  They differ from defilers in that Warleaders are designed to be reactive healers, they recover from damage dealt, although the Field Promotion bubble is a powerful proactive tool.  Warleaders also have several fellowship buffs to select from to best suit their group.

Heals can be done both proactively and reactively. Targetting through freep DPS classes can give you a very good idea of who the creep target is, and you can heal through them to the creep. A proactive approach is far better than a reactive due to the very long cast time for both single and group heals. The bubble also takes approximately 3 seconds to go off, so use it early when needed. With a large freep force, they can take off a half health creep before your bubble even goes off. Also with healing, it is important to reduce the aggro on yourself. Ensure that the DPS classes keep you cleared of NPCs if they want a heal. The single target heal can be cast when under attack from one NPC or freep, the group heal is nearly impossible. Within a raid, heal your group unless designated otherwise, pay attention to other creeps and heal them, especially other warleaders/defilers. For burst healing, alternate between the single and group heal.  I tend to single heal through the freep's primary targetter (when known) and use the group heals to cover my group.  

In raid vs raid battles, when the reavers go in lead off with the group heal to help offset the initial freep raid burst DPS.  Bubble will be put on any reaver in danger and wargs told to get out (they can't live in a freep ball).  Alternate between the single and group heal, using the large 15 minute cooldown heal when necessary.  When under attack from burgs/champs, try to kite them through any web the earth down to get clear (or at least a break), as you won't be able to get a group heal off with them on you.  Wargs do well in clearing warleaders so don't be afraid to call for backup.  Also defilers can use their fear to give you a break away from the interrupts.

Make sure to use food as much as possible for these situations as the power bar will be drained very quickly.  When strictly healing with high incoming damage, Commander's Stance is preferable for the sizable boost to heals.  If something needs to die quick, consider Brawler's Stance but be ready to switch out of it ASAP with the huge healing penalty.  Don't forget to keep contributing damage regardless of stance, ensure target forwarding is on and simply use your shouts through whoever you're healing through at the moment.  When under heavy attack or being disrupted by burgs/wardens, go straight brawler stance and shout away.  Get those heals off with Power of Fear traited and the AoE 0 cooldown Quit Whining and Fight.

Rezzing in a small group should be done based on the situation.  With Mines of Moria changes, the recharge rate to the AoE rez was significantly nerfed. It is critical to have the raid leader to designate when to rez to maximize the effectiveness of each rez and not to double rez too quickly.  While the prior standard used to be rez when 2 creeps are down, unless there are a plethora of warleaders it's best to use it when 3-4 creeps are down to maximize this valuable skill.  It is critical to know that if you die when your rez goes off, everyone you rez will be at the rez circle instead of where you were when you hit the button.  If you are going to die, don't hit your rez.

Snap Out of It is a useful skill (after it was unnerfed, restoring its ability to remove roots).  Stuns generally wear off fast enough to not burn a Snap.  If it's in a raid situation, give it a second or so for pots to be used before you use the snap on anyone else still CC'd

The Banner of Terror is a very strong weapon against freeps, when possible, stand off a bit to get out of combat then place the banner as close as you can to the freeps. If there are multiple WL's around, coordinate with them to try to maintain a constant banner presence on them (note the duration and recharge times).

The absolute best conjunction for a warleader is yellow, Wight's Rot. This will significantly refill your power. When grouped with weavers and wargs who can open conjunctions in a PvE situation, have them hold their CJ's till you need the power and in range for yellow.
