I had hybrid sniper/burster build at begin of this session, but I liked only burster part of this build, because its funnier, was PvPing in Hinkley, just hold room in which your team is, if someone rushes in, he'll probably die on crit burst instantly, if your team shoots someone in other room and they shooting back, run in and burst nearest, if there're too many people, run back after, or else continue untill they are all dead, etc. SG bursters are fun in Hinkley. I suggest to make 21% or 16% crit build with x2 BRD one-hander based on p90 and 10mm smg, you may also try to use AR without one-hander, but p90 better. AR is an excellent weapon for hybrid builds, but anyway with a time you'll choose only one part, the only good thing in hybrid, is to scare snipers by rushing them with p90 and do hit-and-run from minigunner shooting his eyes, but later I chosen to always burst, even vs miniguners, we just run to each other and trying to be hit not on 1st hex and then fast step to him and burst, SG bursters are also good in... guarded towns, because they're always know how to have fun there.
So SG-burster = fun, easy to obtain weapon and ammo, good in Hinkley, because p90 > mini, and enemy snipers will always think bad about you after some games with the same people and try to kill you 1st when see and start to panic and run away if they know that you're somewhere near.
