Nomad is a Legion melee semi-carry hero that puts an emphasis on skill, decision-making and reflexes more than the other heroes who rely on head-on damage output. His skills are designed to reward competent players by using deception and guile to outsmart opponents. His skills are:
Sandstorm,
Mirage Strike,
Wanderer and
Edge Counter(Ultimate).
This video preview pretty much sums it up. I hope this guy doesn't become another overpowered hero.
