Geez, I know people said fire rate doesn't affect the burst rounds but I didn't know it was this bad. With +100% fire rate, which is effectively 1.5x her fire rate Paradox empties her clip...a burst and a half faster.
Now granted Paradox is worst case scenario since she has a 5 round burst compared to the other 3 round bursters but it still shows how useless fire rate is.
