I cannot do an important attack while in a noisy place (including the game sounds, which I have always had off).
I also cannot improve my attacks by having repeated friendly challenges. However much I try I only lose my tracks, and get worse at it. So I end up performing all my attacks fresh, from scratch (after scouting though).
As a result, I am an average attacker... or less than; but enjoy playing games, for their entertainmentthis one in particular.
