I hate PzIVs

Toblakai,
I can't really answer that, because the last time I played a QB was at CMx1 times.
It very much depends if an AI plan is available and how well it is suited for the force composition on both sides and the tactics the player applies.
But since the AI in regular scenarios in most cases is no challenge, how could it be a challenge in a QB?

I am wondering that a PBEM player with such an outstanding win/lose ratio like you, is playing QBs against the AI. A honest question: How is that possible that you win against almost every human player but find playing the AI interesting?
