RE-45 burst?

What's happening with the re-45 burst? I thought it was supposed to be only temporary? I miss the re-45 auto, and would be pleased if it returned to the floor. The burst is cool but it's kinda garbage in close range, because of the charge time and is not a good idea to switch to it as a secondary, as soon as you do that every other gun already melts you before you can even get a shot off, hell even opposing players switching speed is faster then the charging speed of the burst!! I use that gun all the time, and that's when I noticed that the gun is garbage now. Bring back the re-45 auto, the burst sucks!
