I've played Gears 1and 2 multiplayer, but never got into them because of the lack of a consist midrange weapon. Has Epic put a good go to weapon in the game or are they still all spray and pray.
Retro Lancer = Dominant mid-range gun (if you can handle the recoil and spread).
Hammerburst is good at all ranges if you've got a quick trigger finger.
Retro Lancer and HB are both good choices. Hell, even the regular lancer is good. I feels much better compared to the previous games.
The HammerBurst has always been the best MidRange weapon. Even in Gears 2.
Hammerburst - If you pull the LT and then click RS, you get a great iron-Sight view.
