After having been found guilty in 2 out of 4 charges by a six-person jury, Jonatham Majors has been fired by Disney/Marvel Studios. Majors was found guilty of reckless assault in the third degree and guilty of harassment. He was found not guilty of intentional assault in the third degree and not guilty of aggravated harassment in second degree.
The fact they made him at all capable in his fight against Kylo
He gets easily defeated by Kylo Ren.
I am with you on the overall wasting of potential there (he should have been Rey's first "apprentice" by the third movie), but at no point was he holding his own against Ren.
