I'm more neutral on the subject. I like the centralized focus on occults in this game, though I would like Spellcaster Vampires. That said, besides the fact that this is very unlikely to happen, if they were going to do anything occult, I'd rather they focus on Fairies and perhaps Genies.
And especially a focus on adding an occult never before seen in TS4, to help give the game more reasons on why you would choose it over its predecessors. I'd love to see the team try their hand at Superheroes, Reapers, or perhaps add Dragons for the people who've been consistently hoping for them. Maybe Android or Cyborg Sims, hey, why not. Maybe give some current occults a refresh. I'd like to see Aliens or Mermaids get something cool.
