1. Valeera Sanguinar
To be fair, I haven’t spent much time in the World of Warcraft. But I love the idea of Valeera Sanguinar in Heroes of the Storm. After spending a large portion of her life trying to survive childhood and escape imprisonment, she finally found a trusted friend in the human Varian Wrynn. Her reputation as a lone wolf, independent of factions, and her surly attitude are somewhat reminiscent of Valla, but with a slightly more human (or elven, if you like) aspect to them.
According to her lore and art, she’s a crafty and dangerous Assassin, deceiving her enemies with tricks and mind games before swiftly dispatching them in a flurry of bladework. Like her Blood Elf relatives, Fel energies course through her body and make her greedy for power. I think it would be really cool to see her played as a melee Assassin with deadly combos as well as some fantastic escape options like blinking behind her enemies, an activatable stealth, or abilities that would reduce the vision of her opponents. I love melee Assassins, especially high risk/high reward ones, so Valeera would be the perfect Hero to play for me.
