I'd argue that you should be pleased then, because she's VERY MUCH not a sniper.
She's best suited for a mid-range that's closer than Soldier: 76, but a little bit further back then McCree.
She's designed to benefit from high accuracy, but isn't at all built for long range. She
can use iron sights to deal more damage at a distance, but it slows her rate of fire and movement speed. That's mostly just to give her elements that players with a high skill ceiling can make heavy use of, though. It's more a tool to utilize
AGAINST snipers, rather than allowing you to act
AS one.
Firing from the hip has a high rate of fire with decent damage, and while her Coach Gun is a solid mobility tool, it's also a way to keep opponents at her preferred mid-range. Her TNT is on a timer and while it'll go off when the fuse runs out, you can shoot it to detonate it, thus letting people who're really good toss it just over a shield and skillshot it out of the air. In tandem with the Coach gun, you can also use it at close range and back off quickly and damage clusters or force back an opponent who's a bit too close.
That brings us to B.O.B.
B.O.B. is a mid-range Ultimate, where he dives in and pops a group up into the air — meant to let Ashe shoot them out of the air if there's a cluster she's being overwhelmed by at her optimal range. Then, from that point until the Ultimate ends, while B.O.B. shoots at targets like a turret until he leaves, B.O.B. also acts as a stationary character — you can armor/heal/boost him, just like you can freeze/sleep/discord him, and he can capture/contest points & push/stall payloads.
I have a feeling she'll see a lot of synergy with Wrecking Ball, Orisa, Torbjörn, Doomfist, & Lúcio because of all the displacement and area denial they're capable of in tandem, and how well they can cover that general range, and harass the enemy out of spaces that're too close or too far.
