Just know that vampires and werewolves have been balanced out, vampires permanently have jump boost, and if no damage taken, they will never have to feed, yes ofcourse they cannot walk outside, but that is simply solved by putting blocks above you. Werewolves can only eat meat, even in human form, this makes it harder for them because 1. they have to start a farm or 2. they have to buy it, and meat is not cheap.
During their transformation they also suffer from hunger 3, so they need to eat a lot faster. Yes, bloodmoon has Strength 3, silvermane has regen 3, and witherfang has speed 3/4. BUT, when vampires have bloodlust on, they gain strength 2, speed 3, and hunger 2. So the races have been balanced out. Also when you feel like you are losing from a werewolf, just simply take wolfsbane and a silver sword. Simple as that.
