For Inferno and Stronghold, heroes with ballista are good and can be leveled up. For other castles, it's not very effective. But in general, it's worth recruiting a ballista into the main army: it doesn't slow down the army and provides extra damage for neutral creatures (250 HP is still a significant amount, plus stats).
It's not just about damage; you can also successfully use the ballista to deal with slow, low-morale neutral creatures with weak troops. The damage is minimal, but it's there. Golems on levels 111-113 can be defeated in any quantity. I wouldn't underestimate the ballista, although it's not a good idea to heavily invest in artillery. Unless, of course, Gurney can do something serious with it.
