After some changes in the filters and assault bot buff I gave a chance to my old idea and try to play using no conditions and assaults only. I've improved my previous AI (mentioned above) and (surprisingly) managed to win with 2000 ELO player once while being in Master League (see the picture).
It was match 827677, unfortunately not replayable now. After that I tried some more improvements, played a hundreds of matches and ended in Diamond League with ELO around 1500. Not bad for such a dumb AI!
Now the problem is that this AI goes not well with the idea of daily maps, so I guess I'll give it a break. Hopefully it will do better with random maps, so I will get back to it as soon as it shows. At the moment I share my AI with you, because you can find some clever tricks there. Enjoy!
Oh, BTW: all of you who has lost against me in last 10 days - how do you like them apples?
