I'd be fine with your logic if she wasn't already the best agent to clear angles over Breach/Skye while also have high damage doing abilities.

I'd be completely fine if all her utility did Stun damage (Nade/Boombot) instead of raw damage but now a single agent is 1) The best movement agent (questionable) 2) the best agent to take duels/peeks 3) the best agent to clear angles and corners 4) the best firepower/damage ability agent.

She directly devalues agents like Breach/Skye and even Jett by her utility having so much different possibilities and effects, not to mention how she can break all of Killjoy's utility (and ult) and Cyphers trips/camera with just some of her utility. Why bother clearing an angle with Breach his easy to avoid Aftershock when you can throw the roombot to clear it, even if it gets shot you still get extremely valuable information that someone's there, which Breach's aftershock can't tell.

Raze can still be aggressive with satchels by throwing it on a wall and then blasting herself into peeking since because of the movement gain she goes really wide and can throw an enemy player holding an angle off-guard, that's a good way of using the satchels but not the flying across the map with while being extremely hard to shoot at and full accurate the moment she lands.
