Well the best I see for a weredruid would be BotD Zerk unless you can get a magic or rare weapon with enough IAS to hit 4fps AND do decent physical damage.

With the BotD zerk you'll hit 5fps which is still slower than a paladin zeal.

As for the choice of spirit, I think sage is much more useful than Heart of the wolverine because it gives so little bonus AR and Damage compare to the Sage's Life bonus.

Share the Pr0n, Not the lag
