I got an indirect karma by telling PaulBellow for 1v1 losing streak, which I neglected 1v1 for a while.
Someday, I will come back playing 1v1 but I might not have enough preparation, from mental and tactic. I could spend my time to make a custom ai but perhaps there is something else I can do to make at least preparing 1v1 battle, other than adding more than one AI in singleplayer and sending 1v1 loss to Godde.
