I like this Pack and the ideas presented here .
However there are some problems I hope they could fix:
Some of the abilities are too lackluster for example : Command , maybe you could command them to give you money or to steal from another sim.
Or to use the command ability to make gathering collectibles easier for example:
command a sim to fish or look fro frogs or look for minerals etc
it would be great if the influence emotions ability could toggle to also work on the sim casting it.
There is basically no difference i could see between turn to bat (Cost 2 Knowledge) and turn to mist (Cost 6 Knowledge)
for role-play purposes I wish they add a blood type preference to the likes and dislikes list.
the weaknesses are either too crippling or too inconsequential .
eternal sadness makes your sim sometimes have +50 sadness which completely cripples them if it was not dealt with.
Thin skin makes it very risky to send a sim to work since after they get back from work they like to stand still for a few minutes under the sun
On the other hand Day Phobia and Guilty Drinker are very easily resolved bay having the Carefree trait
The worst thing about the Pack in my opinion are the aspects
In the Vampire Family Aspect it makes no sense to become good friends with 5 of your offspring while the reward is that your command ability against them can not fail
The Master Vampire and the Good Vampire aspects both have the survive for 20 / 19 days as a Vampire Task which is in my opinion the worst task in the sims 4, it is just there to inflate gameplay time
