What if Henry VI, lived up to his father's strengths, the late Henry V and wasn't so mentally unstable. Additionally, can the regency be improved to better hold their position in France by giving concessions to the Burgundians, such as Henry VI's regents brokering to give the Burgundians a crown of their own in hopes of appeasement. Would this, by the time of the end of the regency give England a chance to conquer the rest of England, and would the regency have the power to hold the parts England had taken in the first place. Additionally, as a third POD, say Joan of Arc is burned for heresy due to her claiming the lord had spoken to her. Lastly, would the War of the Roses still happen, or does Henry VI's lack of insanity prevent it, and if the Lancastrian should fail in say a few generations, what might happen in that alternate WOTR.
