This specific feature was on our schedule and it was announced be to added to the game but after long conversation with rest of the team and developers we were able to cancel this update. We are fully aware that you guys, our community, do not like this specific feature and you consider it as killer of the game. We strongly agree with you. However, we were supposed to get new version of % tactics. As you may know, German version has tactics with limit of 25%. Our limit would be only 5%. So it is not that drastic but you know ...

Right now we do not plan to add % tactics. But we would like you guys to at least see or try it (maybe???). So right now there is no answer I could give to you. This specific feature is not fully cancelled, it was jut removed from our schedule and put aside for now. We might come to that point were developers will bring this topic againand we will need to discuss this matter with them.
