I agree, my bases weep because of this. However, our saurus cav are still way too expensive for what they do. Most other cav are either way cheaper, or way better. Those damn chaos knights actually got cheaper, but are still meh compared to the skull crushers.
I get the charge off on any other cavalry, which all have str 4 now, including the horses, I have to eat all those hits before I even go and lose 2-3 saurus cav before I even get to go. So yeah saurus cav not really worth, I would rather take terradons, rippers, or more monsters.
