I’m guilty of rolling at least two of each class with different races and opposite gender toons. I keep a detailed character directory in a Word document listing my alts’ assigned specs and professions by server. With the prospect of more allied races on the horizon, my directory is ever-changing, but this is what I have currently:
Core Horde Toons:
Goblin Rogue (Female) (Horde Main) / Nightborne Hunter (Female) / Blood Elf Demon Hunter (Male) / Highmountain Tauren Warrior (Male) / Mag’har Orc Monk (Male) / Zandalari Troll Shaman (Male)
Core Alliance Toons:
Worgen Druid (Female) (Alliance Main) / Human Death Knight (Male) / Void Elf Warlock (Female) / Night Elf Priest (Male) / Lightforged Draenei Mage (Female) / Draenei Paladin (Male)
Sub-Alts, Group 1 (Class Duplicates):
Kul Tiran Druid (Male) / Dark Iron Dwarf Shaman (Female) / Worgen Rogue (Male) / Human Monk (Female) / Void Elf Hunter (Male) / Night Elf Demon Hunter (Female) / Blood Elf Death Knight (Female) / Nightborne Mage (Male) || (Need: Male Warlock, Female Warrior, Female Priest, Female Paladin)
Sub-Alts, Group 2 (RP or Farming):
Night Elf Druid (Female) / Worgen Hunter (Female) / Void Elf Rogue (Female) / Goblin Shaman (Female) / Nightborne Priest (Female) / Zandalari Troll Druid (Male) / Blood Elf Mage (Female) / Night Elf Demon Hunter (Male) / Worgen Death Knight (Male) / Gnome Warrior (Female) / Tauren Monk (Male)
