In dota 1, heroes had 2 “names”. 1 was the actually name of the hero
(“Traxis”) the other was the title of the hero (“Drow Ranger”). For Dota 2, Heroes were set to have 1 name, although some dota 1 players still say the heroes by their others names.
This is made to help you get familiar with all names and if someone says “Naix”, you realize they mean “Lifestealer”.
