Heroes of the Storm Build Guides
What is Hero Damage exactly? Was it supposed to be Basic Attack Damage? Because if it is, then damn, 300 bonus Attack Damage for 15 seconds is an insane amount.
Does damage reduction from [Iron Will] stack with positive Armor? Also, does it only affect Basic Attacks?
Does Vulnerable from [Piercing Howl] stack with negative Armor? Also, is this not just Malfurion's [Twilight Dream]?
I do not think it is a good idea for [Execute] to grant both Unkillable and Unstoppable. It just becomes mandatory.
[Block] is a poorly designed talent. It does nothing most of the time.
What is Rage? How does he gain/restore it?
Heroes need to have at least 3 talents per level (excluding Heroic Abilities) to allow for build variety.
I assume [Furious Charge] transforms [Takedown] into Diablo's [Shadow Charge]? If that is the case, then it needs some drawback, as a ranged, point-and-click 1 second Stun is an incredibly toxic effect.
Can [Giant’s Blood] be used while Stunned/Silenced?
Why would one ever pick [Nexus Blades] over [Redemeer]?
