IMHO building bonus vs Camels should be at least made it clearer for players because as it of today, nobody knows what damage a building arrow will dealt to a Camel without testing.
For example, even if in the editor the Castle shows 0 bonus atttack vs class 16 (Camels/Ships/Saboteurs), actually it has a big bonus against them; AoFE team should work on it to make it clearer for all players (eg. "Each arrow fired by buildings dealt +50% damage vs Camels"), or something like that, but try to make it clearer if you can...
