I vote Winston. I think he can be a better hero with slight adjustments. Maybe give him 1000 health. Or add an ability. During ultimate beast form, press RB to drop a bunch of bananas, cooldown 2 seconds. You can drop a total of three bunches during ultimate form. Any player, including the enemy team, gains 50 health.
I think ball or doom needs to be reworked.
You rework problematic heroes, Winston is not problematic he’s just not meta right now. Very big difference.
