I heartily endorse the comments of Kurando, Kraellen and Zen_Blade regarding teppo. You guys save me a lot of typing! When it comes to posting I am really lazy.

In heavy rain I would stop ALL firearms from working completely. These were matchlocks after all. Even when I try to prime and load a flintlock in a downpour it is impossible to keep the powder dry. I can only imagine how hard it must be to keep a match burning too.

I beleive teppo and archers in fortresses and citadels should fire better in any weather than their opponents outside, including having more ammunition.

Kurando's remarks about MP and SP differences are especially pertinent with all of the discussion afoot concerning unit balance and cost. SP can compensate strategically for unit stat variations in ways MP cannot. CA must tread carefully IF they intervene here to avoid breaking more than they fix.
