Great Bombard didn´t have any bonus against Elephants, but other cannon-type units do:
- Bombard +50
- Culverin +35
- Cannon +55
- Great Bombard: None
Surprisingly, I was recommending using bombards against elephants, but it turns out that the Great Bombard doesn´t have that bonus.
I think for balance it should be added, now that its base damage has been reduced quite a bit in the last patch (150 → 70). Also i repot it as a bug because i didn´t know if it was deliverate or not, or they forgot to adds the extra damage for the ottomans proper cannon-type unit.
