I disagree. His current configuration allows for a lot of strategy. If you got a well-parked Bastion, especially with a Mercy taking care of him and teammates coordinating with him, you can mow down everything. I’ve seen it on my team, I’ve seen it on the opposing team.
It’s a strong character that involves team work. The others have to cover for him for it to work, and you won’t always have people who are willing to do that, or know how to do that.
Scrap tank mode cause it’s insanely bad. Give him a attack helicopter mode. Would be badass, and it would give bastion a chance to use his ult to reposition himself.
