and just remember i could e.g. with storm warriors / warriors of muspelheim make my vampires immune to lightning / fire .

Both of those spells only give 50% resistance. Wrathful skies with storm and false horrors can hold off a very large number of vampires. High-level fire magic will also quickly decimate their numbers. Flames from the sky can also kill huge numbers of vampires.

If I was planning for a game to Last to turn 100, then I would probably actually forge soul contracts with my slaves, depending on what nation I'm playing. Devils are superior troops to vampires, and if you can afford 100 vampire lords, I could afford to have 70-92 soul contracts. These also have the added benefit of being able to survive when you use heat from hell and firestorm.
