This melee Thrall is pure burst and self healing with (W) to keep foes from running and your (Q)Chain Lightning for harass or finishing. This build allows you to THREE SHOT squishy heroes (Raynor, Tychus, Tyrande,Nova, etc.) once you get your final talent on windfury. Basically, windfury will hit twice, then 3 more times on its last strike allowing your frostwolf res. to give 10 stacks and reduce ability cds by 2.5 sec from windfury alone. As long as you stack Seasoned Marksman, your autoattacks from windfury should be enough to kill almost anyone.
