>More than Tracer
I mean, yes, very much yes.
Thrall, the main character of Warcraft 3 more or less, which was the lead up game to World of Warcraft, who was the Warchief of the Horde up to Cataclysm.
Illidan Stormrage, the poster boy of The Burning Crusade, a huge character that's been marketed to hell by the company due to how recognizable and iconic he is.
Arthas Menethil, aka The Lich King, the big bad of Wrath of the Lich King, a huge lore character who was a protagonist/antagonist of Warcraft 3. Him getting an expansion to WoW all to his own kinda drives in how major he was, and he's still to this day iconic as hell despite being killed off.
Sylvanas Windrunner, maybe not soo much nowadays since Blizzard wants to push her as a Mary Sue antagonist, but for a long time, she was arguably WoW's strongest female main character, and due to her design, personality, and associated lore, was insanely iconic.
