Least favourite occult

Of the three you listed, I also have to vote spellcasters. It takes so long for them to learn the spells I actually want. At least Vampires and Werewolves have some control over how their powers develop. Vampires don't need to visit the vamp library every day for weeks hoping this time they find the Tome of Alluring Visage and the five mythical Heart Fish they'll need every time they want to use it. >.<

Of all the ones available, plant Sims and aliens are the most disappointing. Especially when they could have easily upgraded plant Sims with Strangerville.
