They don't have a promo for it, they just HAVE collateral as a natural ability. But yeah, whether stripped too far down or not, the review has them as useful still.
EDIT: Here is the xml for Arsonist. Where is the city defense reduction they used to have? The Bombard part that reduced City defenses? Collateral is against other units but does Nothing to reduce city defenses LIKE they used to do.
I don't see it. I do see BombardRate = 3. But you can't Bombard the city defense with the base Arsonist. I have tried.
Is it now attached to the City Attacker Promo? Is that the Promo that gives them the Bombard=3 ability?
And what was their Bombard rate before?
