I'm playing a VTM 20th edition campaign with my friends, and they are really liking it, the only thing that is not great is the combat.

Sometimes the group battle just one or two enemies, and it's fine, but now they are at war with the Sabbath, and the Camarilla is helping then in some battles, but then the combat turns into something like 10 versus 5, and then it gets a little boring, for me, because I'm controlling all the characters and for then, because they need to wait 10 actions to do something.

I know that one solution would be to just reduce the size of the battles, but battles of this size are really great for my storytelling at the moment, is there anything else I can do?
