Here's the defensive part, which I feel is the most important. When I get some more time, I'll try and add more details, then do aggro, ae aggro, and offensive sections.
WARRIOR DEFENSIVE
Starting off you're going to want to keep the following on cooldown/always on: Brace for Impact, Blade Guardian, Paragon Champion, Geometra (charm clickie), commanding voice (I've heard this stacks with shoulders and that it doesn't, so I still use),
Imperator's command, Shield Reflect (might as well throw it in the ini somewhere)
-Use Battle Leap for the self-buff once every time you zone (can use on eye of zomm)
MASH KEY - Knee Strike, Gut Punch, Shield Sunder, Call of Challenge, Throat Jab, Taunt (with hastened taunt you generally don't need to worry about availability + it has an aa proc)
I also keep Warlord's Resurgence + any other self-healing clicks on CD and they parse surprisingly high.
Mitigation Rotation - Keep these up on a 5 minute timer: I would run these abilities back-to-back at all times, unless you're trying to stack them for ultra tankability.
1. Finish the Fight (161,162) 3m/5m
2. Dissident Shielding (451) 60sec/5m
3. Guardian's Bravery (197) 48sec/5m (From the Warrior Anguish BP, must have)
4. Diplomatic Immunity (161,162) 12sec/5min (From anniversary quest)
General ability stacking:
Anything that shares a SPA will not stack with another ability of the same SPA. It will use the SPA which is most effective.
55-Enchanter runes and our synergy ability which procs off of shield sunder (use this all the time and max this aa if you haven't)
161-Spell Guard (absorb dmg)
162-Melee Guard (absorb dmg)
168-Defensive mitigation (Ultimate stand, Defensive proficiency from our weapon stance etc.)
197-Skill damage taken - (warlord's bravery and Guardian's bravery)
451-melee threshold guard (Dissident shielding, Roaring shield - bp click)
452-spell threshold guard (Diss shielding)
450-dot guard (enchanter spells, jann’s illusion)
You're going to run Courageous Defense in the combat ability window at all times unless something better is up like Ultimate stand.
Always use shield flash on incoming, but you can only use with DW/shield. It's 2 ticks frontal mitigation.
Generally, you will save these abilities for Named as they have longer CD:
1. Fortitude Disc (18 sec of invulnerability, almost always use of Furious because of BP focus)
2. Last Stand/Ultimate Stand (3m/10m30sec 45% melee mitigation)
3. Warrior's Rampart (melee threshold with hate mod) will use this up quickly
4. Roaring Shield (3 min/hit limit, melee threshold BP click
5. Mark of the Mage Hunter (absorb spell dmg)
6. Spire of the Warlord (90sec/7.5m, they’ve recently made this useful, I believe it uses 168 SPA primarily now)
7. Resplendent Glory (%increase to healing, can save or can use on CD)
8. Warlord's Bravery (SPA 197, recently got an upgrade, but still a 20min timer)
9. Warlord's Tenacity (Increase health by a lot, also functions as an emergency heal)
Stances: I've left out the Offensive mods because this is the defensive section
1. Defensive Prof II (Shield equipped. I rarely use unless I'm fighting a named or brand new to an expansion)
-Increase Shield Block 10%
-Increase proc rate 20%
-increase melee mitigation by 12% (168 SPA)
-Absorb melee damage: 5%, 2000 max per hit (162 SPA)
2. Dual-Wielding Prof II (Almost always use)
-Increase chance to parry by 40%
-Decrease chance to dodge by 30%
-Increase melee mitigation by 6% (168 SPA)
-Increase proc rate by 20%
Note on the Honed Wurmslayer from an earlier post:
I looked at a sample of 250 mobs in a RoS tier 1 zone with the wurmslayer, then replicated the same 250 mobs while swapping the wurmslayer with the tier 1 ToV war weapon.
Wurmslayer - Ave hit taken = 4269
Tier 1 ToV WAR Weapon - Ave hit taken = 4464
So, looks like the Wurmslayer still took off an additional 195 on every hit compared to the War weapon.
Also, my dps increased by 17k when the wurmslayer was replaced, obviously.
