I voted for fairies as I would really like them back in the game. I would also like to see the return of werewolves and genies (with ability for genies to have their own secret lot - inside their lamp).
Mostly though I would like mermaids to be given an update to give them more properties akin to vampires and spellcasters. I absolutely adore the mermaids in the game and it's so disappointing that they're not as developed as other occults.
I haven't played with Plantsims in TS4 yet but I loved them in TS3 and I can't understand why they're not a permanent occult life-state this time around.
