The latest Overwatch update unleashed the new hero Brigitte into the game's competitive mode. Just a few days later, Blizzard has already announced nerfs. 

This is probably a good thing, if the competitive Overwatch forums and subreddits are any indication. Most of the threads complain about how Brigitte has a stun and a knockback, both on short cooldowns. Her kit was largely designed to help her deal with quick flankers like Tracer and Genji, but it's also a nightmare for tanks like Reinhardt.
