It depends what races are available on each side. So I play more Alliance than Horde. I like the lore of many races in the both sides but I like playing some races and I don’t like playing some other races in the both sides too. Liking the lore of a race =/= playing a race for me. Of course I like the lore of the races I play. Here what I play:
Alliance:
- Human
- Night Elf
- Wildhammer
- Draenei
- Man’ari Eredar
- Dark Iron Dwarf
- Pandaren
Horde:
- Troll
- Mag’har Orc
- Zandalari Troll
- Nightborne
But some new races could change this. I wait some races for a long time now and I would like to play some of them.
Alliance:
- Broken
- Mogu
- Arakkoa
- Jinyu
- Vrykul
Horde:
- Forest Troll
- Mok’Nathal
- San’layn
- Saberon
