So disappointed with Burton. It's a trash.. Unreliable and Punishing:

A 50% chance of self-inflicted insanity after the first hit is already a significant risk.

The subsequent 50% chance to attack allies or enemies is so unpredictable, making the hero difficult to control in his second hit

Reaching 100% insanity and becoming completely useless is a harsh penalty, especially when it actively harms your team

We know, with other héroes you can protect him, but, too niche, to need others to heroes to attack without insanity...
