Maybe if you look at it from a average Evil Piece perspective as Rook types are strong but slow so they are weak to fast multi strike attacks while Rooks are resistant to magic atacks due to durability. While Knights usually have weak defense due to their focus on speed so it they are bursted down by a high powered magic attack or a strong impact they will be defeated.

But in practical combat nothing is absolute as we see. Ise is weak to technique types due to his inexpericence and the technique types being really skillful such as Cao Cao, Kiba or Apophis.

But even ultimate technique cannot pieces ultimate power as Cao Cao admited he could not beat full power EJOD Vali in Vol 12.

Also note that Wizard types can be any of the other three roles as depending on the magic they specialize in. For instace: Rias, Akeno & Roseweisse are Wizard/Power types, Sona & Brynhild are a Wizard/Technique types and Asia is a Wizard/support type.
