Geoff Goodman is the principal designer for Blizzard’s Overwatch developer team. They constantly communicate with the community on various issues regarding the development of the game and any balance changes needed.
They have always announced future updates and categories that they are working on through the official battlenet forums.
He has now reveled in a comment that the developer team is working on a rework for Bastion. bastion is one of the least player heroes in the game. While he has a lot of damage, but his low mobility makes him extremely unviable in competitive matches.
The comment can be found on the battlenet forums.
I’m actually working on some changes for him right now. I’m not quite sure when these changes will hit the live game, we’re still testing different things internally.
