That was not the case as soon as you started the Star Wars Battlefront after you downloaded it. The DL-44 is so powerful that you were taking out other players long before they even had a chance to make a move.
Remembering the two other weapons had a similar impact, the developers have done their best to bring them all back to the same playing level. The balance patch has seemed to do what it was supposed to and now the game is ready for the next major update.
Both the publisher and the developer have confirmed a free update for Star Wars Battlefront this month that is not going to fix every little thing you think is wrong with the game, but it will fix plenty of things gathered through user feedback over the last few months. User feedback is used in each update so it is important that bugs and other gameplay issues are reported.
