The idea behind a rework is to change a hero’s gameplay and purpose. If Doom gets a tank rework, i’d want him to be good like the others.
The reason why Doomfist was moved in the first place is everyone, and I mean everyone, including professionals, played Doomfist like a DPS hero when he was in the tank role.
So they shrugged and maybe said,
“Maybe Doomfist always was meant to be a DPS hero.”
