I think the sniper style should not fit to an agent that is known to have close fast style combat araund her opponents because a sniper just stand still and fight far for the target. Even in the animation Official Duelists Cinematic Trailer, of her battle against Phoenix, shows that she have a close and fast combat style.
I think it's boring to use operator on her. In the way she is now, Raze is better rushing down in a close combat than her. I just stopped playing Jett because I was forced to use operator.
Maybe the operator could be nerfed when used on Jett, with a negative interaction with her abilities, or her abilities should just be changed to be coherent with the lore
