Striga said it best as to why Drolta and Erzsebet lost when they SHOULD have won

Two whole seasons later and this is still true. Hell when you think about what vampires did this season this statement becomes fact

• Erzsebet wanting to become god

• Drolta wanting to bring back sekhmet

• Alucard whom was going to stop the apocalypse by himself before he saw Richter

• Olrox trying to protect Mizrak without arousing suspicion

And they really should have won had Erzsebet gotten over the learning curve of her powers and recoved It would have been a clean kill with Drolta .
