not sure what gamemode you are referring to, but at least for 1v1 being able to fire into the base sector is pretty much all on-maps have going for. usually they're more a bane than a boon to your army composition due to high popcap and lack of static, clumped-up targets - at least compared to 2v2 and onwards. plus, you'll most often be firing into the FOW when attacking the base sector, so scatter will be so high that you'll actually need quite a bit of luck to hit anything at all. combined with the recent nerf to barrage cooldown, i think being able to target the base sector is not really an issue.
I was refering mainly to 2vs2
If all they have goin for them in 1vs1 is base fire, they probably shouldnt be there at all
The scatter is not a problem, with the RoF and barrage lenghts, youre still bound to get good hits and wipes sooner or later
If needed, they might be compensated by some other buff
