Power creep is subjective and even before Brigitte was released, there were heroes that could be considered as “power creep” when they were put together in the same team.
And my example still stands. A lot of abilities or heroes can be power creep in the right meta, yet I don’t see people yelling for nerfs.
The hate against Brig must come to an end. She didn’t need the recent PTR nerfs and even less a rework. People just need to adapt and switch. And if the current meta is problematic, we can still add new heroes to change it or buff certain heroes. No need to destroy a hero like Brigitte.
