It's just all the complaints about town attacks.......So it is really worth all the hassle, or should I just try out a vanilla vampire?
Not sure if a DG Vampire is any different than a regular vampire, other than maybe some differences in the Clan Powers. You can always load up a save, fork it, become a Vampire and see how you like it. If not, load the earlier save and play on.
As to the town attacks, those are easily manageable.
1. Never travel in or to a town or settlement at night. Your presence in the cell at night triggers the attacks so they won't happen if you are not out in the city at night.
2. If you need to Fast Travel to a town or settlement, then save first just in case you arrive after dark, then you can reload, and wait a bit before you travel.
3. If you want to have the town attacks, but minimize the death to NPCs you might need, then do this:
Be in the city, in an interior cell. Wait until 6PM, then wait again until 8 PM, then wait again until 10 PM. This will trigger the scripts that have the NPCs commute from work to home. You go out at 10 to play with the vampires. Once the NPCs are in their beds, then mostly what you have in the towns are generic guards so the attacks won't kill anyone you need.
