The 321 speed on something meta needs to go. It’s so boring that every high lobby consists of Lucio + kiri/moira.
Speedboost is one of those abilities that can ruin entire games if you’re not mirror it.
So I make a wish and let Speedboost retire, it’s time. 
Coordination is what makes it a high ranked lobby imo. That’s like saying you don’t want Dva and Tracer to say who they’re gonna dive
At least it’s not poke 
Great example of how not to balance a game.
Tracer is for a different topic, but honestly I rather play dive then any rush comp whatsoever.
