GUYS, devs will never bring old combat style back. I can give you a tip how to be good in it - choose better Hero. Pick Conqueror and do only dodge-bash-spam. Or pick Jiang Jun and spam dodges ... it is so simple and easy. You will win most of the fights. Do not pick Heroes which can not bash-spam! ... othervise you will cry.
I change my main Hero to bash-dodge-spam Hero and I am winning like never!
