That's your fault for relying heavily on blink. If it puts you in a vulnerable position that's your fault not the fusion rifle. And you can't be sniped with a fusion rifle. Please show me a video of someone being one shot with a fusion rifle with full health from anywhere past mid range.
Yes, blame the reliance on blink instead of the lack of psychic powers predicting every single move and position of enemy players at any given time .
Sometimes, you just get ohk'd by a fusion rifle from a ridiculous range.
Not every single death is like that, but it happens enough to warrant a (slight) nerf, seeing how weapons are being nerfed left and right.
