It's amazing how much raid buffs can affect fury warrior dps. My typical raid composition is
Prot/ret pally (he's ret for single tank fights, which is Dreamwalker and BQL so far)
Holy priest x2
You will note the buffs I am lacking are
Melee haste - Frost DK
Minor speed - Moonkin/Ret pally
Attack power multiplier - Enhancment shammy/Blood DK/MM Hunter
Bleed debuff - Arms warrior/Feral Druid
In addition, the strength of earth totem we get is not talented.
According to the simulation in Landsoul's spreadsheet, the lack of these buffs reduces my theoretical maximum dps by 1,100, or around 15%. That's a massive difference. I wonder if other classes are so reliant on such a wide variety of buffs to do reasonable dps.
