Hi,
I like the game a lot, but the serve is way unstable and it really annoys. Even if I create player in editor with 100%-stable serve, it's still quite a nightmare. Getting in the top of green zone doesn't mean anything - he can miss it many times in a row. I understand that it's probably done to make the game more realistic, however, I believe that it's better to make a serve itself more complicated, but fully dependent on a human player, not some random probability.
