Inspired by Hex's beautiful RK skill thread, the following is a list of Warden skils and Gambits with a few unique passives thrown in for reference. I'll add levels on each later. Just wanted to get them up.
Gambit Skills:

Spear, Shield, Fist. These three skills make up the core of the Warden arsenal. You use them in various combinations (that you'll see later) to open Gambits that give you your prime strength. The Gambit Default is the skill in the Gambit UI until you use the other skills in an order that turns it into a unique Gambit. You can actually drag the Gambit Default to a quickslot so that you can keybind it as well.
Gambit Trait Skills:

These are the three primary Warden legendaries. The trait unlocks new Gambit skills that allow you to add two icons to the Gambit UI at a time. So if you need to get a certain type of Gambit off faster then usually, keep that legendary slotted and use one of these skills to start that combo up quickly.
Weapon Passives:

These are inherent bonuses that Wardens get to certain weapon types. They come at level 15 and 30. The level 30 one (shown) is slightly more powerful than the 15 and overwrites the previous bonus. The 4th Legendary for Wardens is an additional 5% to Spear, Sword, and Club damage and more buffs to those weapon procs.
Stances (read: Tobbles):

These are the three main Warden stances. Defense/ICPR, ICMR, and offense. I've found Determination to be the most universally useful in dangerous situations. That's a lot of ICMR. And coupled with your Heal over Time Gambits, can mean your morale doesn't move for a very long time. If you need to kill something extra fast, Recklessness definitely does the trick. When you're worried about respawns or pathers and need to get in and out fast, that's your best bet.
