What a difference the extra triggers make in the test design! Is it more work? Yes. But it's also better. You have improved the capability of this test to find defects and you will have more confidence in your game when it passes tests that use all of the triggers. Defect Triggers were not created with any one particular test methodology in mind. They are effective whether you are testing at the beginning or the end of the project and whether you have meticulous test designs or you are just typing in test cases as you go along. If you choose not to use them, you are adding to the risk of important defects escaping into your shipping game.
