Okayy, im not pretty sure if this is really important anymore as 1.03 fixed the fact that artillery tks dont give minus points but anyway. In my experience when you kill someone with arti, it doesnt give minus score to commanding but teamwork score! When i got my staff officer ribbon, which was before 1.03 the commanding screen showed that i had a score of 28 when i got the ribbon. Then i checked my stats and it said i had -22 teamwork score so if we add up a bit...

28+22=50 which would make it clear that even though i killed a few ppl with my arti, it didnt matter because teamwork score got minuses but commander score did not!

What do you think? Make any sense?
