Like Issei's DxD form, those are final trump cards to use. They aren't going to use and reveal their most powerful form of their Longinus right out the gate against each other. Those are not to be used lightly. Issei has basically been fighting in his True Queen Mode. What reason do those two have to use their most powerful forms against each other? Breakdown the Beast isn't something to be used so lightly. Neither is Truth Idea.
