It takes hours if not days to reset valor when there’s not XP boosts and you can get them in under an hour in a master Nightfall. It’s a bigger time investment and it won’t invalidate nightfalls since PvE players aren’t going to just start grinding PvP if they don’t like it in the first place and it would give PvP players a slower means of master working gear. Being forced to play Nightfalls as the only means of masterworking gear goes very, very far against “play how you want”.
