If Brigitte wanders on her own to either chase kills or disrupt the enemy team with stun, she has used her only escape. When I do anything that stupid, the enemy team immediately makes me pay for it. Case in point, I mentioned in a previous topic that Rein players have become smart enough to know that if I’ve used my Stun, he’s free to Charge me to death.
That sounds more like the enemy team not punishing Brigitte than Brigitte playing poorly.
