Same with the buffed tactics. We were told what tactics were improved, but not how much - we just have to figure it out ourselves. But it's way better than just buffing some of the tactics without telling which ones.
Totally agree on that one. Updates to engine must be announced properly.
Existing algorithms however are a totally different animal imo. For instance, one thing that was too much for me, and I cannot remember where I read it unfortunately, were some very specific details about defensive zones - who has X % chance to defend whom, on what type of shot etc. I believe this should remain "inside" info.
On the bright side - those posts usually bring on a lot of discussions and input and sometimes very good improvement ideas are born, so I guess I can live with that at the end of the day! Much better than waiting for a response for months, as it used to be not long ago!
