Windfury is good for hitting face and literally nothing elseI don't think I like the fact that hunter can have a better windspeaker in their decks depending on what they get. RNG is too much here. Roll huffer then give it windfury, +3 attack and similar makes a big difference in hunter. It's so much damage.
I always thought people undervalued windfury effects.
When it comes to board control, windfury does fuck all.
The only WF cards that ever got played seriously were Al'kir and Doomhammer (since they can attack right away),Raging Worgen (because OTK combos) as well as Whirling Zap-o-matic(since the WF comes basically for free).
