Signets were not listed because they don't cost adrenaline or energy. Dolyak Signet and Healing Signet are the two most common signets you'll use as a Warrior. Keep in mind both have very serious draw-backs. Dolyak Signet makes you nigh-immoble, so make sure you won't need to move once you use it. If you feel you will need to reposition after casting it, bring along a shadow-step skill (Death's Charge works). Running Warrior's Endurance, Dolyak Signet, and Death's Charge will turn you into a teleporting infinite energy tank. Healing Signet causes -40 armor. For those who don't know how armor works, that means it doubles the damage you take while casting it. Makes sure you're running a block stance while casting it (and make sure that it won't end on skill activation).
Skill synergy is paramount too. Consider running a hammer tank, with Gladiator's Defense, Protector's Stance, and Renewing Smash. Now you can keep up near infinite block, and protect your team too (requires you to stand with the backline, so it's better as an off-tank, or when facing enemies without AoEs). Running Brawling Headbutt and Steelfang Slash in any adrenaline fueled build will give you a constant boost in adrenaline gain, and give you a solid interupt on nasty enemy skills. A Warrior/Paragon build that uses Spear of Fury along with Barbed Spear and Blazing Spear can jack up the teams DPS, while being able to spam "Save Yourselves!", with either a Strength or Tactics spec.
For tanks that run energy intensive builds, the use of a Zealous weapon is highly recommended, especially if you are using an IAS stance (keep in mind, you can only activate one stance at a time; you'll need to decide whether or not attacking faster is more important than blocking). Even though most IAS stances list an increase of 33%, that translates to 50% more attacks. Blunty, if two identical warriors, without attack skills, auto-attack the same target, the warrior under the effect of a 33% IAS stance will do 50% more damage. So, for terms of DPS, no skill is more important to a warrior than one that provides IAS.
I prefer to run Strength/Adrenaline builds. I'll run Flail, Enraging Charge, Lion's Comfort, Defy Pain, "For Great Justice!", "Save Yourselves!", plus two attack skills, either energy based, or the Brawling Headbutt/Steelfang Slash combo, to increase the rate at which I spam "SY!". In my opinion, Defy Pain is the best and most versatile warrior primary tanking skill. With a 20 second duration, it's easy to keep in up indefinitely durring combat. At 16 Strength, it gives +314 HP, +20 AL, and -11 DR. All from one skill. This puts the average tank at 120 AL vs physical, 100 AL vs Elemental. Math time:
NPC deals 100 physical damage with attack 1, and 100 elemental damage with attack 2 to Tank A, who is wearing max AL armor. Tank A takes 50 damage from attack 1, and 70.71 damage from attack 2. The same NPC then attacks Tank B, who is wearing the same armor, but is also running Defy Pain at 16 Strength. Attack 1 does 24.36 damage, while attack 2 does 39 damage.
Now, “SY!” is also, in my opinion, one of the best ways to protect your team:
An NPC boss hits your team with Searing Flames, at 20 Fire Magic, dealing 230 damage (130 base, x2 for boss damage, and we’ll pretend the whole team is on fire because you’re in lava). You monks, mesmers, ritualists, and elementalists all take it on the chin at the listed damage. You assassins and dervishes get hit for 193.41 damage. You paragons and fellow warriors take 162.63 damage, while the rangers laugh it off at 115 damage.
The boss hits you team again, but this time, you’ve cast “SY!”. The monks, elementalists, ritualists, and mesmers all giggle as they take 40.66 damage. The assassins and dervishes tell knock-knock jokes while they take 34.19. The paragons and warriors have an arm wrestling match while they take 28.75 damage, and the rangers shed a single silent tear for the boss as they take 20.33 damage.
The above assumes that no one wears a shield or has native damage reduction, and doesn’t use insignia that boost AL. “Save Yourselves!” is a warrior PvE skill gained from either the Luxons or the Kurzicks. It’s +100 AL for your team, for 4 to 6 seconds, at the cost of 8 adrenaline. It’s pure hotness.
I’ll add more tidbits as they present themselves.
