Tier 1: Take BLOCK if the team has an excessive amount of Auto-Attack heroes. Otherwise, SHOT OF FURY will help get that initiation of Fury going as well as help with keeping up WRATH OF THE BERSERKER.

Tier 2: FURIOUS BLOW. More damage; more money. This is a spin build, but sometimes you need a W to secure the kill at the end, or for taking camps. If you're going to take FEROCIOUS HEALING at level 7, then take BOON OF THE ANCIENTS instead here.

Tier 3: SHATTERED GROUND. Yep, more damage on W for when Whirlwind is down. FEROCIOUS HEALING is really good for sustain during your Wrath Wreckings. 10% Health on a 10 second cooldown for 10 Fury is pretty good. Take it and BOON OF THE ANCIENTS on 4 if you think you'll need the extra boost.

Tier 4: WRATH OF THE BERSERKER. We like to wreck with our spins.

Tier 5: LIFE FUNNEL is really the only choice here. We want to win with our spins.

Tier 6: ENDURING WHIRLWIND. More spin; more win. If you're having trouble being CC'd or need more sustain then Stoneskin is probably your option. Against auto heavy comps, IMPOSING PRESENCE can be the best choice.

Tier 7: Even though "FURY OF THE STORM" sounds like something a #Spin2Win girl might like, I think the choice here is to upgrade our WotB.
