BT > WW > 1sec > BT > Sunder > 1sec
This is the rotation if u dont get the Instant Slam proc.
BT > WW > SA > BT > SA > SA > is the tryhard version which wont make u lose any DPS at all. Ive done it, ive seen it.
Its better to use Sunder than to do nothing.
If u have 2 fury warriors in raid, which u ussualy do, u will get 5/5 in no time cos the aplications stack.
Its true that on some bosses its not worth doing, for example LK 25m hc phase 3, where u constantly get teleported in Frostmourne and lose stacks, but again, if u are moving and u have a free GCD, use Commanding Should, use Demo Shout, use that god damn Sunder Armor.
On Halion 25m hc, where once u get in Shadow Realm, u can get 5/5 and have them for a long time, and buff almost every DPS inside, i NEVER see a single warrior do it.
Also, one more thing, as a fury warrior u should be the one doing, DPSing, Spikes on Marrow, Adds on Lady, Killing the Mage on Gunship, Helping with adds on DBS if u see range DPS is strugling (care for overagro, dont get hit by them at all cost), DPSing the oozes on PP, just whenever a wild add apears that needs to be bursted down, u are the one that should be doin that cos Fury Warrior is best at high burst DMG without any preparations. Make sure u never overagro and die. U wont top recount/skada if u die, ever.
Again, its all about principles, u wont wipe cos there is no Sunder Armor on the boss, ppl wont lose **** ton of dps, but u will be a better player for the raid.
If Sunder Armor was so irelevant, ppl wouldnt have used it on Retail, and Retail Fury Warriors guides wouldnt tell u to do it.
Marrow, Lady, DBS, Rotface, Fester, BQL, and LK p1, maybe p2 if u are able to track it and not lose it cos of valks. So there is few bosses in icc where stacking isnt worth doin, only cos u have to switch targets constantly, but again, if u can track it and know when to use it, u can keep the stacks on PP aswell.
P.S. UNBRIDLED WRATH IS THE MOST USELESS TALENT EVER. Dont use it. AT ALL. If u REALLY want to waste talent points there, and u are in some delusion that it actualy gives u any kind of DPS, waste atleast 1talent point less and get PIERCING HOWL. Piercing Howl is usefull on fights like, Lady: slowing the adds, DBS: slowing the adds, LK: slowing valks, and on top of that, when targets are DAZED, u do MORE DMG with HEROIC STRIKE. U can use it on trash constantly aswell, its helpfull in RDFs when u have to run away from adds that can hurt u, and so on...
Talents such as Booming Voice and Commanding Presence are way more usefull for the raid than Unbridled Wrath will be usefull for urself, even if the chance for that talent procing was 1000%, it procs from ur offhand hits only, that occurs every 2sec, that alrdy gives u **** ton of rage, its a fkin chance on hit, and its fkin 1, only 1, 1 rage for crying out loud.
Lets waste 4 talent points so i can have a chance for 1 extra rage when my offhand hits, yaaay!
