I was my guilds dedicated DPS warrior in TBC and the first raiding warrior on my server to go PvE arms that I know of... within a month of me going arms almost every guild on the server had their DPS warrior switch to arms after they all saw our WWS reports, the only reason I know that is because almost every single one of them from every guild sent me tells asking me to explain the rotation and spec (this was late SSC/The Eye very early Hyjal/BT).
Unless you're a mega baddie and all of the rogues/hunters in your guild hump, your DPS done + the added DPS to the raid (which is threat free since the tank gets the same damage increase) will most of the time make you the highest damage dealer in the raid by far unless it is an anti-melee fight... to be honest, there is NO
reason to have a fury warrior in the raid past a certain gear point (once you get your first cats edge drop), rogues/hunters will do more damage so your ONE dps warrior should be arms for almost all T6 and up content in TBC.
Until you have at the very least the Kael'thas sword
, Badge Axe
, Gorefiend axe
, one of the third tier BS weapons or season 2 or greater arena 2h'ers, I wouldn't bother with PvE arms. Archimondes sword
is what I used up until wrath was released, I had originally specced PvE-MS with World Breaker
, it was ok I guess but since mace spec blew for pve it really wasn't worth it at the time so I went back to fury until I got the Twinblade from Kael'thas then shortly after the Cats edge.
Edit: Also, Sulfuras, I don't know for sure what you posted that video for but the only DPS warrior they had was arms and he was still holding his own on a relatively anti-arms warrior fight (had lots of running around) he was hovering around 8-10th spot on the meters most of the fight and then when you add all of the added damage from blood frenzy it would put him in first by quite a bit since 7 out of their top 10 DPS were all physical damage dealers.
