Is it culture, lore, appearance, architecture, zone, faction, etc?
I will start
Blood elf
I like the architecture, lore, zone, appearance, almost everything.
High elf
Ive always wanted to roleplay a High elf mage or hunter, ever since i saw the NPC’S in Dalaran and Stormwind, and heard their smooth voice similar to that of the night elves. I was also a big fan of Warcraft 2 Alleria until she turned void.
Void elves
At first i was not a fan of themm, but they grew on me. Especially now that they have black hair. I think they are really fun to roleplay especially in the light-based alliance faction.
though i think they lack the Nzoth eyes to really make them cool.
Night elf
lore, architecture, female apperance is nice. Overall great race to roleplay.
Trolls
Great and tragic lore, very underrated race, and amazing shakira style dance :
whats not to love. Even dont mind the toe nail.
Undead/ Undead elves
cool and tragic lore, and kinda creepy at times. Very fun!
Vulpera
ignoring horrible furry steroetypes, Vulpera are actually fun to roleplay. They are nomads which is flexible in terms of where you want to roleplay, and they have an amazing lore and hearthstone racial. I remember sitting in a camp fire in the barrens and just chatting with a group of nomad vulperas. then we went to Azshara to swim in the swimming pool with the goblins, before heading to the barrens again to sell and trade some items with passing travellers.
