Also, you can tap one direction twice to compensate for the diagonal. For example, instead of pressing down, down-left, left for Aura Bolt, you can press down, down, left and it will work. So for Bum Rush, try pressing left, up, up, right, right, down, down, left, left.

I don't know why more people don't suggest or know this. It's by far the easiest and most effective way of doing it, and in every Blitz topic like this there is at least one person who mentions it. It should be common knowledge for the regulars of this site by now.
