Yeah I'm that way with the recon class. I'm not a sniper so I just put that gun in there and use the class in a slightly different manner as an smg class with the motion detector and the anti-tank stuff.
In fact it seems like nearly half the time I die, that's the gun that kills me. A lot of people are using that gun most likely in the recon and medic classes.
It's a bit of a shame that they don't offer a larger range of weapons for all classes. It seems like the next ones unlock in 20+ levels for me.
I think they should have given the engineer a different weapon class and made the SMGs for all classes since they're the most balanced. Like, if they use the shotguns from single player that had a bit more range, I think they would be good for engineer.
That way it's broken up by:
assault = mid to long
engineer = close to mid
medic = mid range
sniper = long range
And SMGs provide good close, great mid, and good long range.
Would have made all the classes more appealing.
I also don't like the idea that you have to unlock things like the repair kit or med pack. I normally don't play as engineer, but if there is a situation that calls for the role, it is a bit annoying that I don't have access to their namesake ability until I play as them for a while as a normal shoot and kill soldier.
