Suggestion on the Mayans

No you didn’t understand, i was asking since the obsidian arrow is applied on archers it is weird that this didn’t include the pulm archer because it is archer!!! This is just all about.
I am actually want the +6 attack to be nerfed, at least by making it imp tech not castle, i think they should even make it +5 or +4 vs buildings not +6!!! And make the cost more expensive to research it.
