We did testing tonight and my Dragon Breaker is just slightly worse than the 2x crit chance, 3x crit dmg breaker that Imrulkz has (and his was just 19% so his would be even better if it was maxed out! Based on our testing, I'm pretty sure the 2x chance / 3x dmg configuration is best because my weapon would be stronger than the 1x chance 4x dmg breaker for sure. 3x chance is a waste because you already crit a LOT with 2x. This doesn't take into account the General's Helm where it may be the correct strategy to care more about never running out of rage even if it means sacrificing power. Still though, my weapon has swag written all over it even if it's not the best, amirite?
