I'd really hate for it to be lag cause that's not fixable for me. Where I live we have only ONE internet provider via satellite and they are slooooowwww! No, switching to cable or even dial-up isn't even an option because there are no power/phone lines anywhere nearby. (Our electric comes from a generator, and yes, we live middle of nowhere. Lowest cost to put in power lines has been quoted at 25k.)
So I'm really hoping it might be something that is gear or tactics related.
My tactics so far - keep the infantry right in front of the archers, start hitting the baddies w arrows as soon as I can see them, blast everything with the solar power. LOL this basically results in "watch everything die before the big bad even gets near you".
