to be honest i dont know if it work or have effect as i cant tell using it and not. like you say condition work on your team and from someone like you(jeeves) then it must have some effect.
i use attack from the first min till i can get a goal try to kill the game early. then use condition to hold on, attack again if need to. how do we tell if its working? i try playing without using bonus still manage to win dont know if my oppo using it.
