Autoblock was on the last time I checked,but I havent seen anyone using it so far.
Yes,there is cav(I think me and the devs are the only ones that have one tho xD),but,as others said,map design deals with that and there wont be any bot-trains because the AI is smart.And by smart I mean better than the average cRPG player,they even chamber...
And about CSR:I sadly didnt play warband when the first version was released,but I heard of the remake.Sadly,when I checked back early this year,the dev announced that he had to quit it because of another,bigger project.
