There are 2 types of player in this game.
Those who play the First Person Shooter Overwatch, and those that play Arcade Overwatch.
The problem that causes threads like this and any other “rework/delete hero X” to appear is that in fact there is no FPS Overwatch, it died with Sombra release. It will not be back, remember it if you enjoyed it, forget about it if you thought it was boring.
Blizzard will never remove characters.
