Accuracy is good however. If it were up to me, I'd remove them from open battles all together and just have them as deployables in siege battles: then you could have ballistae in your siege armies without having to sacrifice troop numbers. But alas, I do not work for CA. You should also note that balancing is being worked on for v.1.0. which I assume will address this sort of issue.
All that being said, I'm not sure how it's possible that you could be insulted by a minor facet of the unit cap mechanism.
