Windfury Totem: Summons a Windfury Totem with 5 health at the feet of the caster. The totem enchants all party members main-hand weapons with wind, if they are within 20 yards. Each hit has a 20% chance of granting the attacker 1 extra attack with 445 extra attack power.

Basically it’s a 20% chance for an extra buffed attack. WF is a flat 20% damage increase on your >main hand< - end of story. (not counting the extra AP on the WF hit, but let's leave that out for now).
Isn't that insane? Just by being in a shamans group you have a 20% chance on every hit for an extra attack. With a 3.8 speed weapon, a Retribution Paladin will swing 15.8 times a minute. Windfury effectively increases this to 19 times. Seal of Command will proc approximately 8 times during this time.
Windfury Totem is an air totem spell that Shamans receive at level 32. Every five seconds, this totem will pulse a 10 second duration main hand weapon buff to all members of the group within range. This weapon buff will NOT be applied if any other weapon buff is present. Using things like Sharpening Stones, Mana Oil, or Poisons will prevent you from gaining the use of Windfury.
[Average main hand white damage + (WF Atk Bonus Damage * Non Normalized Weapon Speed)] * 0.2
Where WF Atk Bonus Damage is 41.2 for 2/2 Enhanced Weapon Totems, 36.55 for 1/2, and 31.8 for 0/2.
Windfury is the best melee buff in the game for Ret Paladins, Warriors and Combat Rogues. It doesn’t help Feral Druids (It’s because it’s a Weapon Imbuement, and Cats don’t use weapons.) but having an Enhancement Shaman in your group is still of benefit from Strength of Earth (SoE) totem for 86 STR.

There’s data to show that WF can proc off of SoC as well. The general rule of thumb is that you can only proc each once in a sequence started by an auto attack. Examples would be auto attack —> SoC —> WF and auto attack —> WF —> SoC. As stated, this takes your SoC up to ~8ppm and your WF procs up to 25% instead of 20%.
Feral druids also benefit from the enhancement shamans unleashed rage which is 10% increased attack power for 10 secs after the shaman crits(which is a lot).

WF totem doesnt increase paladins dps by 20% ^^
Simply because pala is not only AAing as many ppl think… we use even SoC, CS, Judgement (Cons, Exorcism)
20% would be if the pala didnt use any ability above listed…
And try to look on Recount reports, WF totem is 9-10% dps increase for most paladins, depends on play style.
