Okay so yoda's training sucked too but it worked. And Luke was able to turn Vader at the end but couldn't handle his own nephew who hadn't even killed anybody yet? It's just needs a little more explanation. Maybe you're right about Rey and Kylo but the ppl in these movies with all the high level force energy at a young age seem to be from the same family.
My other question was why Phasma was the only one with ray deflecting armor, they need to give that **** to the troops lol.
