It's fine. A good sniper vs a good arbalest, the sniper wins 100% of the time. It's aim assist is also overstated. It really only has high aim assist inside mid range, or around 30m. After that its accuracy drops off significantly. The biggest thing that people are actually confusing with aim assist is how it handles flinch. It is easy to maintain a target when getting shot; in part due to its zoom, but also due to the fact it has a charge time. Having a charge time allows the user to correct their shot even after it has been fired. So in short. No, it's not a problem. The problem is a lack of understanding from a large portion of the community how the gun, and linear fusions in general work; their strengths and weaknesses, etc.
