This is the BfA PrePatch version of HeroDamage, if you want to see Legion simulations, you can go here.
Those simulations are constantly updated. If you don't see your class or some simulations are missing it is because either it's not finalized on SimC end or on our end.
You can find more informations on the state of SimC implementations here.
Keep in mind that those data can be considered expiremental since PrePatch lasts only few weeks.
