I am new to making Hero Concepts, so expect the wording to be clunky and the numbers to be off. Apologies.
While I get this will never happen, one of the things I love about Heroes of the Storm is how it combines radically different universes together. I thought it would be really cool if the Avatar universe arrived at the nexus! I plan to do a concept for every Element (I'm thinking Toph and Aang as Tank and Multiclass respectively. I've already created Katara as a support).
ANYWAY, AS FOR THE ACTUAL HERO:
Prince Zuko is meant to be about a AA hero that has a large number of rapid fire but reasonably easy to hit skillshots. His Fireball ability increases his DPS and he can reposition himself with Fire Jets. Blademaster mostly seems good only with talents built around it, but it offers a different way to play the hero.
