What would you like to have changed or added to Vampirism

There is an option to prevent vampires from turning into bats while in the End, it would be a nice if this could be extended into a full dimension blacklist, so that it can be prevented in other dimensions (like the Nether and modded dimensions).

Does this make the mod experience more balanced?

Yes.

Can you provide additional resources (etc. textures or models)

N.A.
