Fury Warrior/Mistweaver can be tricky because they’ve got more options than you will offensively and defensively at the start of the game where you are the most likely to over use cds and get behind.
What worked for us was to run Castigation / Feather / Sins of the many with barrier & radiance honor talents, I don’t know what his third was, on Disc & to run CW/TL/FoWT/HC/WDP on WW and I ran HHS, Grapple, & CTM. My disc runs radiance traits and I have some random assortment of junk that isn’t worth mentioning. Usually I am on the warrior for the entire game because I can deal with his damage as a ww better than I can manage the warrior if he decides to sit on the priest the whole time. Aim to deal with a lot of the damage as efficiently as possible by using your utility. You have so much more than he does. If your priest is free to smite and heal the majority of the damage with PTW, Atonement, and Smite absorb then make sure you are using your CTM on CD and keeping up with the damage to live into dampening.
Piercing Howl is the only slow the fury has and it’s AoE.
You should be able to play pillar with your disc as a ww (Howl into WW aura should still be faster than an unbuffed warrior with only howl snare so it’s important that you are in range of your priest). He will clear your snares with Bloodthirst (Thirst for Battle) so you have to constantly watch them and be ready to refresh disable. If you are playing around the pillar right you should be safe from most charges and if you are safe from charges then warriors are likely to either start bloodthirsting you for Thirst of Battle, or pairing charge with heroic leap. The goal is to get the warrior to use his own mobility cooldowns because between feathers and port/tl/rolls you guys have more. You want to reduce as much uptime from the warrior as possible. This can all happen without Paralysis, Scream, or Barrier. The smarter you are with Disable Root / Feathers once you are out of charge LoS the less you will have to commit to the uptime. This will leave you with more options to deal with the things that really hurt and that’s what you’ll need when dampening stacks up high enough.
Warrior uptime is everything for them so it’s really the one goal during the entire game for us.
Battle Trance from using Raging Blow twice
Thirst for Battle from Bloodthirst
Reckless Flurry buffs auto attacks
Battlefield focus is just problematic
Simmering Rage & Pulverizing Blows buff rampage, which is buffed by carnage, which gets more bonuses from Recklessness and Enrage.
Once you limit the uptime you also limit the self healing. Since Fury doesn’t have Defensive Stance and the self healing is tied into doing damage you can create a lot of pressure with Mind Bender + Dark Archangel + SeF with Leg Sweep and a sometimes I’ll commit grapple weapon depending on how late into dampening and what the remaining cd on stormbolt is, or what map, etc. Positioning is really important here because you want to make sure that you are not over committing afterwards. A lot of times you’ll see the enraged regen on the ToD and once that happens there really isn’t a point into committing more than you already have at that point. If you use a Para to setup or you were able to get a feather+scream on the healer then you’ll use the opposite to follow up.
If it’s a map that doesn’t have a pillar for you to play around then you just default to playing like we did in Legion. Drag the warrior to his healer over and over again. Go for the double fears, double sweeps, cleave with FoF/WDP during DA, keep an eye open for close range casts you can /roll + Kick. If your healer is vulnerable so is his.
The biggest threat, after warrior uptime, is Crane. The best way to deal with crane is undeniably barrier but once you drop it you’ll immediately get feared. It’s definitely possible to see the Intimidating shout coming and it’s so easy to move out of range when you do but it’s not a very reliable way to deal with it. So like I mentioned above - when you use para to setup, have scream to follow up for crane, or the reverse. Continue to deal with the warrior through mobility because if he ever pops cds without storm bolt when he has no mobility then he is throwing.
With that said - Storm Bolt and/or leg sweep is the one thing you can’t really do anything about. If you can FoF to lower his damage, If you can grapple, If you can root, just do it. You will lose to the game to either a storm bolt or a leg sweep. Whichever one your healer can’t trinket. Once you are in dampening if you can get them to start using cds to deal with your setups then you are in a position to win. Both the Warrior or the MW is a kill target for a WW.
Some alternatives are Disabling Reach for you to better root the warrior. Masochism for your priest on those maps where you have limited line options. Penance gets kicked more often than SM.
If I think of anything else I’ll add it. I’ve never tried writing out my strategies to someone else for how I go about beating a comp so I hope this was understandable in some way.
I wrote that for WW on the old forums but perhaps some could apply it to there own specs.
